I have spent the better part of three years hauling easels up hiking trails, setting up on windswept coastal cliffs, and chasing fast-moving cloud formations with a brush in hand. Plein air painting, the practice of creating artwork directly from nature rather than from a photograph, demands a very specific kind of paint. The wrong tube will dry out before you finish blocking in shapes, or worse, leave you with a muddy mess by the time the light changes.
The best paints for plein air landscape painting need to balance three competing demands: they must remain workable long enough to capture shifting conditions, they have to be portable enough to carry miles from the car, and they should offer the pigment strength to translate real-world light onto canvas. After testing dozens of options across oils, watercolors, water-soluble oils, and acrylics, our team narrowed the field to seven standout sets that actually perform outdoors.
This guide covers the specific paints we have relied on in the field, broken down by medium so you can match the right set to your workflow. If you are also shopping for gear to round out your kit, our guide to the best gifts for artists includes several plein air essentials worth a look.

1. Gamblin 1980 Oil Color Exclusive Set – Premium Artist-Grade Oils
- High-end student grade oils at real value
- Solvent-free gel allows clean blending outdoors
- Bonus wood panel saves buying a separate surface
- Excellent pigment load and buttery consistency
- Limited to 8 colors in the set
- Heavier than watercolor kits for long hikes
I first packed the Gamblin 1980 set on a four-day painting trip through the Blue Ridge Parkway, and it quickly became my go-to oil set for fieldwork. The 37ml tubes hold substantially more paint than the 12ml starter tubes you find in most beginner kits, which means I can lay down large sky washes without rationing pigment. The eight-color selection covers the warm and cool primaries I need for mixing natural greens, plus a few earth tones that handle shadow work beautifully.
What sets this set apart for plein air use is the included solvent-free gel. Traditional oil painters know the hassle of carrying turpentine or mineral spirits into the field, which is messy, smelly, and increasingly restricted in national parks. The solvent-free gel lets me blend and thin paint without hauling solvents, and cleanup at the trailhead takes a fraction of the time.
The pigment load here is genuinely impressive for the price tier. Gamblin positions 1980 as their student line, but the titanium white alone rivals tubes costing twice as much, and the cadmium-free yellows mix clean secondary colors without the chalkiness I have seen in cheaper brands. On a sunny afternoon with the light shifting every twenty minutes, that kind of reliable mixing behavior saves paintings.
The bonus cradled wood panel is a nice touch for studio sessions, though I typically swap it out for linen canvas panels when working outdoors. The stiff consistency of these oils holds brush marks and palette knife textures well, which I appreciate when capturing the chunky, sculpted forms of rock outcroppings and tree bark.
Who This Set Suits Best
This set is ideal for oil painters who want professional working properties without paying gallery-tier prices. If you are transitioning from acrylics to oils for plein air work, the solvent-free gel and forgiving consistency make the learning curve far more manageable. The eight-color palette also forces disciplined color mixing, which actually improves your landscape work over time.
It is less suited for artists who need a massive color range right out of the box, since you will be mixing every secondary and tertiary color yourself. Long-distance backpackers may also find the 37ml tubes heavier than they want for a multi-day trip.
Drying Time and Field Handling
These oils stay workable for several hours on the palette, which is exactly what plein air conditions demand. In warm weather I get roughly four to six hours of open blending time before surfaces start to tack up. The paint remains touch-dry within 24 hours on absorbent surfaces, so transporting finished panels home is less nerve-wracking than with slower-drying traditional oils.
2. Winsor & Newton Cotman Watercolor Paint Set – Compact Field Box
Winsor & Newton Cotman Watercolor Paint Set, Field Pocket Set, 12 Half Pan w/ Brush, Sponge, Bottle
- Ultra-compact design fits in any pack
- All-in-one kit with brush sponge and bottle
- Good transparency and tinting strength
- Excellent value for the quality
- Half pans run out faster than tubes
- Some hues use economical pigment alternatives
The Cotman field box is the set I grab when weight matters more than anything else. On a recent backpacking trip in the Cascades, this kit added barely any weight to my pack while still letting me complete three plein air studies over a long weekend. The snap-shut case is rugged enough to survive being tossed into a daypack alongside water bottles and trail snacks.
Winsor & Newton designed this as a true field box, not a studio set pretending to be portable. The integrated water bottle, sponge, and folding brush mean I can start painting the moment I find a viewpoint without unpacking a dozen accessories. The half pans click firmly into place, so I have never had one dislodge during a hike.
The watercolors themselves deliver the transparency and luminosity that landscape painters need for convincing skies and water surfaces. Cotman is the student line from Winsor & Newton, so some colors use alternative pigments rather than the more expensive single-pigment formulations in their Professional range. In practice, the difference shows up in staining power and granulation, but for field studies and travel sketching, the performance is more than acceptable.
I particularly like how these paints lift and re-wet on the palette. If I need to interrupt a painting session because rain rolls in, I can close the box, wait out the weather, and pick up right where I left off. That flexibility is invaluable when working in unpredictable mountain conditions.
Color Selection and Mixing Range
The 12 half pans cover the essential landscape palette: warm and cool primaries, a few earth tones, and a couple of convenience greens. For painters who want to stretch their skills, this limited selection actually encourages cleaner color mixing rather than relying on pre-mixed hues. I supplement the set with a tube of Chinese white when I want softer, atmospheric effects.
If you prefer working with more colors, the SAKURA Koi Field set further down this list offers 30 pans in a similarly compact format.
Durability for Outdoor Use
The plastic case has survived drops onto rocky trails without cracking, and the thumb ring on the underside lets me hold the open box while standing. The water bottle is small but refillable from any stream or tap, which keeps the kit self-contained for short sessions.
3. Mont Marte Acrylic Colour Paint Set Signature – Budget Starter
- Massive color variety for the price
- Creamy texture blends smoothly
- Works on canvas wood paper and more
- Non-toxic and beginner friendly
- Some colors need multiple coats for full coverage
- Water resistance is moderate once dried
For painters just starting plein air work, or anyone who wants a low-risk way to experiment outdoors, the Mont Marte Signature acrylic set is hard to beat. With 24 colors at this price, you get enough variety to tackle any landscape subject without the anxiety of wasting expensive paint on practice studies.
I recommended this set to a friend who was nervous about taking her painting practice outside for the first time. The non-toxic formula meant she could paint with her kids alongside her at the park, and the fast 2-hour drying time let her pack up finished pieces without worrying about smudging on the drive home.
The creamy consistency is one of the standout features. These acrylics flow off the brush smoothly and blend easily on the palette, which helps when you are racing to capture a sunset that lasts twelve minutes. The semi-matte finish reads well on canvas panels and gives landscapes a natural, unvarnished look.
The main trade-off with acrylics for plein air is drying speed. In direct sun or dry wind, paint can skin over on your palette before you finish mixing. I keep a small spray mister handy to keep colors workable, and I work in the shade whenever possible. Some users report needing a second coat on certain pigments, but for field studies that is rarely a dealbreaker.
Surface Compatibility Outdoors
These acrylics adhere to canvas, wood panels, watercolor paper, cardboard, and even leather. That versatility matters for plein air painters who like to experiment with supports. I have used them on gessoed Masonite panels with excellent results, and they hold up well on toned paper for quick value studies.
Best Use Cases for This Set
This set shines for practice sessions, workshops, and travel sketching where you want color variety without a big investment. It is also a smart choice if you teach beginner plein air classes, since the non-toxic formula and forgiving handling make it approachable for students of any age.
4. Winsor & Newton Winton Oil Color Paint Set – 20-Color Starter Kit
- Generous 20-color range for direct painting
- High pigment load for vibrant mixes
- Uniform consistency across all colors
- Lightfast and permanent formulations
- Smaller 12ml tubes run out quickly
- Slightly stiffer than Artists Oil Color line
The Winton Oil Color set is the kit I recommend to oil painters who want a broad color range without committing to a single limited palette. Twenty colors give you the freedom to reach for a pre-mixed hue instead of mixing everything from primaries, which can be a relief when you are working fast to beat changing light.
I used this set extensively during a workshop in Tuscany last spring. Having access to colors like Sap Green, Yellow Ochre, and Burnt Sienna straight from the tube saved precious minutes when blocking in olive groves and rolling hills. The pigment load is solid for a student-grade line, and the colors mix cleanly without going muddy.
The 12ml tube size is the main compromise here. For studio work, that is plenty. For plein air sessions where you might lay down large areas of sky or distant mountain ranges, the tubes empty faster than expected. I keep a backup tube of Titanium White on hand, since white always runs out first in landscape painting.
The stiff consistency is actually a benefit for impasto and palette knife work. When I want to suggest the texture of foreground grasses or rocky shorelines, the paint holds its shape on the canvas rather than slumping flat. The matte finish photographs well for social media and online portfolio sharing.
Working Properties for Outdoor Conditions
These oils remain workable on the palette for roughly the same window as the Gamblin 1980 set, around four to six hours in moderate temperatures. In hot, direct sun, that window shortens considerably. I always carry a small sunshade or umbrella for my palette to extend working time on bright days.
Palette Building From This Set
The 20-color selection lets you build several different limited palettes from a single kit. I typically pull out a warm-cool primary set plus three earth tones for most plein air sessions, leaving the convenience colors for studio reference work. This approach keeps mixing controlled and prevents the muddy colors that come from too many pigments on the palette.
5. Mont Marte Water-Soluble Oil Paint Set – 36-Color Value
- 36 colors cover nearly any subject
- Water cleanup eliminates solvent hassle
- Mixes with traditional oils and mediums
- Satin finish looks professional
- Not museum-grade quality
- Some tubes may arrive with cracked caps
Water-soluble oils are the medium I recommend most often to plein air painters who love the look of oils but hate the solvent logistics. The Mont Marte set gives you 36 colors for less than what some brands charge for a starter set of six, making it one of the most accessible entry points into this medium.
I tested this set over a two-week period painting coastal scenes in Maine. The ability to thin paint with plain water meant I could work from a single water bottle, and cleanup at the end of each session required nothing more than soap and warm water. No fumes, no solvent containers, no hazardous waste to transport home.
The 36-color range is genuinely useful for plein air landscape painting. You get the full spectrum of warm and cool primaries, plus earth tones, greens, and several convenience mixes that speed up color block-in. The satin finish sits between the high gloss of traditional oils and the flat look of matte acrylics, giving landscapes a natural appearance.
The quality is best described as solid beginner-to-intermediate. These are not the pigments you would choose for a commissioned gallery piece destined to hang for decades, but they are more than capable for field studies, practice work, and finished pieces you plan to keep or sell locally. The lightfastness is adequate for most non-archival applications.
Solvent-Free Field Painting
The biggest advantage of water-soluble oils for plein air is eliminating solvents entirely. Many parks and public lands now restrict or ban solvent use, and airline travel with oil mediums is increasingly difficult. With this set, your entire cleanup kit is a water bottle, a bar of soap, and a rag.
Compatibility With Traditional Oils
These paints mix freely with traditional oil paints and mediums, so you can blend them into an existing studio palette without compatibility issues. I sometimes combine them with higher-end tube oils for finished studio work based on field studies painted entirely with the Mont Marte set.
6. MEEDEN Artist Oil Paint Set – Large-Format Tubes
MEEDEN Artist Oil Paint Set – 12 Colors x 60ml/2oz Tubes – Art Supplies for Canvas Painting
- Generous 60ml tubes last through many sessions
- Smooth creamy consistency for blending
- Strong lightfastness ratings
- Heavy body holds texture well
- Some colors reported as thick with low oil
- Occasional separation issues in tubes
The MEEDEN Artist Oil Paint set stands out for one practical reason: the tubes are enormous compared to typical starter sets. At 60ml each, these tubes hold five times the paint of a standard 12ml starter tube, which means fewer mid-session panics when a color runs dry fifty feet from the trailhead.
I packed this set for a week-long residency where I completed twelve plein air studies. By the end of the week, I still had paint left in every tube, including the Titanium White that usually empties first. For artists who paint frequently outdoors, that kind of endurance matters both logistically and economically.
The heavy body formula holds brush and palette knife marks with confidence. When I am painting the sculptural forms of canyon walls or the chunky textures of foreground foliage, I want paint that stays where I put it. MEEDEN delivers that kind of structural integrity without feeling stiff or unworkable.
The twelve-color selection is built around the core palette most landscape painters need. You get warm and cool primaries, several earth tones, and enough range to mix any natural color you encounter. A few users report that certain tubes arrive thick with relatively low oil content, but a small addition of linseed oil or medium resolves that quickly.
Lightfastness for Outdoor Subjects
MEEDEN rates these paints for excellent lightfastness, which is critical for plein air work destined to become finished pieces rather than disposable studies. Colors that fade undermine months of fieldwork, so investing in paints that hold their value over time is worth the upfront cost. If you also work with metallics in studio pieces, our roundup of metallic paint sets for artists covers options with similar archival standards.
Value Per Milliliter
When you calculate the cost per milliliter, these 60ml tubes are competitive with much smaller sets from premium brands. For plein air painters who go through paint quickly, the economics favor larger tubes every time. The trade-off is weight, so consider your typical session length when deciding between this set and smaller alternatives.
7. SAKURA Koi Field 30 Assorted Watercolors – Maximum Color Range
SAKURA Koi Field 30 Assorted Watercolors with Water Brush Sketch Set XNCW-30N
- 30 colors cover nearly any landscape subject
- Innovative collapsible water brush with storage
- All-in-one kit eliminates separate supplies
- Japanese quality control on every color
- Some specialty colors may need testing for specific uses
The SAKURA Koi Field 30 set is what I reach for when I want maximum color flexibility in a watercolor kit small enough to fit in a jacket pocket. Thirty colors give you instant access to specific hues that would otherwise require careful mixing, which speeds up field work when conditions change fast.
The standout feature is the clever water brush design. The barrel separates into a brush tip and a water reservoir, so you squeeze to control moisture flow without dipping into a separate water container. For plein air painters working standing up or sitting on a rock with no table space, that self-contained system is genuinely transformative.
Sakura individually tests each color through a color matrix process, and the difference shows in blending performance. Colors merge predictably rather than turning muddy, which is one of the most common frustrations watercolor painters face outdoors. The included dabbing sponge handles quick corrections and texture effects.
The 30-color range includes warm and cool primaries, a generous selection of earth tones, and several landscape-specific greens and blues. For painters working in varied environments, from deserts to forests to coastal scenes, having immediate access to the right base color saves mixing time that you cannot afford to lose when the light is right.
The Water Brush Advantage
The collapsible water brush eliminates the need for a separate water container, which is one less thing to carry and one less thing to spill in your pack. I have used this kit on boats, in canoes, and on narrow trails where setting down a water cup would be impractical. The flow control takes a few sessions to master, but once it clicks, you will not go back.
When 30 Colors Outweigh a Limited Palette
Purists argue that limited palettes produce cleaner, more harmonious paintings, and that is often true. But for travel sketching, urban scenes, and rapid color studies where speed matters more than theoretical purity, having 30 ready-mixed colors at your fingertips is a practical advantage that improves field productivity.
Buying Guide: Choosing Plein Air Paints in 2026
Selecting the right plein air paints means understanding how different mediums behave outdoors and matching that behavior to your painting style, climate, and travel habits. The sections below break down the decisions that matter most when building your field kit.
Oil vs Acrylic vs Watercolor vs Water-Soluble Oil
Each medium has distinct plein air trade-offs. Traditional oils like the Gamblin 1980 and Winsor & Newton Winton sets offer the longest working time and the richest color mixing, but they require solvents for thinning and cleanup, which complicates field logistics.
Acrylics like the Mont Marte Signature set dry fast and clean up with water, but that same speed becomes a liability in hot or windy conditions where paint skins over before you finish mixing. Water-soluble oils like the Mont Marte set split the difference: oil-like working properties with water cleanup and no solvents.
Watercolors like the Cotman and Koi Field kits are the lightest and most portable option, requiring only paper, water, and a brush. They re-wet on the palette if interrupted by weather, making them the most forgiving medium for unpredictable conditions. For transporting finished pieces safely, a quality art portfolio for storing artwork is worth the investment.
Drying Time and Climate Adaptation
Drying time is arguably the single most important factor for plein air paint selection. Oils give you hours of blending time, which is ideal for capturing subtle atmospheric effects and graded sky transitions. Acrylics can dry in minutes outdoors, requiring misters, retarders, or shaded palettes to extend working time.
In hot, dry climates like the American Southwest, acrylics become nearly unworkable without additives. In humid coastal environments, oils stay open longer but take days to fully cure, complicating transport. Watercolors are climate-agnostic since they only dry when the water evaporates, and you can re-wet them at will.
Cold weather presents its own challenges. Watercolors can freeze in sub-zero temperatures, and acrylics become sluggish and film poorly. Oils remain the most reliable cold-weather medium, though solvent-free options like the Gamblin 1980 set with its included gel avoid the ventilation issues of traditional thinners.
Lightfastness and Archival Quality
Lightfastness measures how well a pigment resists fading when exposed to light over time. For plein air paintings you intend to keep, display, or sell, this rating matters enormously. Student-grade paints sometimes substitute less stable pigments to control costs, which can lead to noticeable fading within a few years.
The Gamblin 1980 and Winsor & Newton Winton sets carry solid lightfastness ratings across their color ranges. The MEEDEN set also emphasizes archival performance. If you are painting field studies purely for reference and practice, lightfastness is less critical, but it is always better to know what you are buying.
Portability and Packaging
Every ounce matters when you are hiking to a painting location. Watercolor field boxes like the Cotman and Koi kits weigh under a pound fully loaded. Tube sets are heavier and require a separate palette or surface for mixing, but they offer more paint per session and better control over consistency.
Consider how you will transport wet paintings home as well. Oil panels need a carrier box or wet panel holder. Watercolor sketchbooks close and protect themselves. Acrylics dry fast enough that simple separation sheets usually suffice for short drives.
How to Prevent Muddy Colors Outdoors
Muddy colors are the number one complaint among plein air painters, and the cause is almost always over-mixing on the palette. When you combine too many pigments, or when you fail to clean your brush between color changes, the result is a flat, lifeless gray-brown that kills the painting.
The fix is a limited palette of six to eight carefully chosen colors. With warm and cool primaries plus a few earth tones, you can mix any natural hue without resorting to dozens of pre-mixed colors. Clean your brush thoroughly between mixes, and work from light to dark values to avoid contaminating bright colors with darker residues.
Water-based media benefit from letting layers dry between passes, which prevents underlying colors from lifting into fresh applications. For oils and acrylics, use a separate mixing area on your palette for each color family to keep greens clean, skies bright, and shadow areas rich rather than chalky.
Recommended Plein Air Color Palette
A reliable landscape palette includes a warm yellow like Cadmium Yellow Light, a cool yellow like Cadmium Lemon, a warm red like Cadmium Red Light, a cool red like Alizarin Crimson, a warm blue like Ultramarine, and a cool blue like Phthalo or Cerulean. Add Titanium White for oils and acrylics, plus Burnt Sienna and Yellow Ochre for earth tones.
This selection lets you mix convincing greens from yellow and blue rather than relying on tube greens, which tend to look artificial. The warm and cool versions of each primary give you control over color temperature, which is what makes landscapes feel like specific times of day and seasons.
FAQs
How do I keep colors from getting muddy during plein air painting?
Muddy colors come from over-mixing pigments and failing to clean brushes between color changes. Use a limited palette of six to eight colors with warm and cool primaries, work from light to dark values, and wipe your brush thoroughly between mixes. Let layers dry before adding fresh paint to prevent underlying colors from lifting.
What are the best colors for plein air landscape painting?
A strong plein air palette includes warm and cool versions of each primary: Cadmium Yellow Light and Lemon, Cadmium Red Light and Alizarin Crimson, Ultramarine Blue and Phthalo or Cerulean Blue. Add Titanium White plus earth tones like Burnt Sienna and Yellow Ochre to round out the set.
What is the difference between plein air and landscape painting?
Plein air painting is the practice of creating artwork outdoors directly from nature, while landscape painting is any artwork depicting natural scenery regardless of where it was created. Plein air is a method, landscape is a subject. A landscape painting can be made in a studio from a photo, but plein air work is always completed on location.
Can you do plein air painting with acrylic paint?
Yes, acrylics work for plein air painting, especially slow-drying formulations like Golden Open acrylics. Standard acrylics dry very fast outdoors, which is useful for layering but challenging for blending. Use a spray mister, palette retarder, or shaded palette to extend working time in hot or windy conditions.
