The Best Gouache Paints and Sets for Plein Air Painting

Gouache is having a genuine moment outdoors. Its matte finish reads beautifully in bright light, it dries fast enough to keep pace with shifting skies, and a compact set weighs a fraction of what you'd carry for oils. But if you've started looking at what's actually available, you'll have quickly hit the central question: acrylic gouache or traditional? And within each type, which brand is actually worth buying in the UK? Choosing the best gouache for plein air work in the UK comes down to more than colour saturation and tube size. Weather resistance, portability, and straightforward availability at UK suppliers all matter just as much. This article cuts straight to the buying decision: what to get, who each product suits, and what to expect once you're standing in a field with a brush in your hand. If you're still weighing up whether gouache is the right outdoor medium for you, the broader case is made elsewhere on the site. Here, we're assuming you're ready to buy.

Acrylic Gouache or Traditional Gouache — Which Is Right for Outdoor Work?

The short answer: for most UK outdoor conditions, acrylic gouache is the safer choice. The longer answer is worth a moment of your time before we get to the product picks.

Traditional gouache handles beautifully. It stays rewettable once dry, which means you can lift a colour, soften an edge, or adjust a tone even after you've moved on. In a sheltered spot on an overcast day, it's genuinely lovely to use. The problem is that it stays rewettable. A shower, a sea mist, or condensation inside your bag on a damp October morning can damage a finished piece. For UK painters working on coastlines, hilltops, or anywhere with unpredictable weather, that's a real risk.

Acrylic gouache dries to a permanent, water-resistant film. Once it's set (usually within minutes outdoors), a light shower won't ruin your study. You lose the rewetting advantage, which means layering and correction require overpainting rather than lifting, but you gain real peace of mind in variable conditions. Both types have their place, and the table below should help clarify which fits your way of working.

Liquitex Professional Acrylic Gouache

Liquitex is the benchmark for acrylic gouache plein air use, and for good reason. The permanent film is genuinely water-resistant once cured, the matte finish holds up well in strong outdoor light, and individual colours are easy to source through Jackson's Art, Ken Bromley, and a range of other UK stockists. Running out of a specific colour mid-project is an inconvenience rather than a crisis.

Jackson's

Liquitex : Professional : Acrylic Gouache : 59ml : Light Blue Permanent

Liquitex Acrylic Gouache Is Perfect For Fine Art, Design And Illustration, Layering, Solid Color Blocking And Mixed Media. This Smooth And Fluid Acrylic Gouache Is Ready To Go Straight From The Bottle. The Acrylic Formula Gives A New Level Of Permanence And Water-resistance With

Jackson's · £8.40

The 59 ml bottle format is the format most UK painters will encounter first, available at around £8–£9 per bottle at time of writing (prices vary between retailers and can change). That's good value per ml for a regularly used colour, but the bottles themselves are a bit bulky for ultralight field kits. The practical solution is to decant into small palette wells before you head out, which keeps the kit compact and prevents wasted paint from drying in bottle caps. For a lighter travel option, Liquitex also produces the Essentials range in 22 ml tubes, which puts together a workable 12-colour set in a far more packable format.

Because acrylic gouache doesn't lift once dry, you'll need to commit to your marks and correct by overpainting. For painters coming from watercolour, this requires a mental adjustment, but the trade-off is a finished study that can survive being slipped into a bag in a light shower.

Best for: UK painters working in exposed or coastal locations who want a professional acrylic gouache they can restock easily.

Holbein Acryla Gouache

Holbein's Acryla Gouache has a loyal following among urban sketchers and plein air painters who want colour that punches hard on the page. The opacity is exceptional, even in a single coat, and the saturation is richer than most competing acrylic gouache ranges. The matte finish is very low-glare, which helps enormously when you're squinting at a study in bright summer light, trying to judge tonal relationships.

Jackson's

Holbein : Acrylic Gouache Paint Sets

Holbein Acryla Gouache Is An Opaque And Highly Pigmented Paint That Dries To A Velvety Matt Finish. In Terms Of Handling And Mixing, It Behaves Like Traditional Gouache, But Because It Is Made With An Acrylic Resin Binder, It Is Water-resistant Once Dry. This Facilitates Layering

Jackson's · £4.30

The range of set sizes makes it unusually accessible as a portable gouache set. The 12-colour school set sits at a genuinely affordable price point for anyone trying acrylic gouache outdoors for the first time. It's not a compromise product: the paint quality is the same as the individual tubes, and the selection covers enough of the colour wheel to make useful landscape studies from the off. Larger multi-colour sets (Holbein produces some expansive ranges) are better treated as a home-base palette from which you curate a smaller field selection, rather than something you'd carry in full.

The main thing to know about the tube sizes is that 12 ml empties faster than you might expect if you're working at any scale. For larger outdoor studies, plan to carry multiples of your most-used colours, or supplement with a secondary neutral palette.

Turner Acrylic Gouache is worth a brief mention here as a well-regarded alternative in the acrylic gouache category, available as an 18-colour set at around £44. It's slightly more niche to source in the UK than Holbein or Liquitex, but worth knowing about if you want another option to consider.

Best for: Painters who want vivid, graphic colour with excellent opacity, and beginners looking for an affordable entry into acrylic gouache plein air work.

Holbein Artists' Gouache (Traditional)

Not everyone wants the permanence of acrylic gouache. There's a particular kind of painting, the quiet, atmospheric landscape study made on a still, grey afternoon in a sheltered valley, where traditional gouache's rewettable character is a genuine advantage. Holbein's Artists' Gouache is one of the most consistent professional-grade traditional options available in the UK, with smooth, high-opacity coverage and reliable colour accuracy across the range.

Jackson's

Holbein : Artists' Gouache Paint

Holbein Artists' Gouache Is Made From Finely Ground Pigments And Delivers A Consistent Velvety Matt Finish. The Pigments Are Selected For High-density Saturation And The Ability To Mix Freely Without Loss Of Brilliance, Opacity, Or Hue Value In Combination With Other Colours. Thi

Jackson's · £4.10

Individual tubes are available in the UK (Jackson's and Ken Bromley both stock a good range) at around £4–£6 per tube at time of writing, making it practical to build a tailored landscape palette over time rather than buying a pre-selected set that includes colours you'll never use outdoors.

The rewetting advantage is real: you can return to a passage, lift a tone, or soften a cloud edge in a way that acrylic gouache simply won't allow. The limitation is equally real. Traditional gouache is genuinely water-sensitive once dry. A rain shower can mark or dissolve a finished study, and finished work stored unprotected will be vulnerable to humidity over time. Work on heavy watercolour paper (300 gsm minimum to prevent buckling when you rewet) and frame finished pieces behind glass. If you're heading somewhere with uncertain weather, keep your finished study flat and sheltered.

Best for: Experienced plein air painters working in sheltered conditions who want the blending and lifting qualities of traditional gouache.

Winsor & Newton Gouache — Set of 10

If you want to try traditional gouache outdoors without spending a great deal upfront, the Winsor & Newton Designers' Gouache set of 10 is the most straightforward starting point available to UK painters. It's stocked at Cass Art stores across the country, available online through Jackson's and others, and sits at around £25–£28 for the 10-colour set at time of writing. For a low-commitment trial of traditional gouache outdoors, that's a reasonable ask.

Jackson's

Winsor & Newton : Gouache Paint : 12ml : Set of 10

The Winsor & Newton Gouache Paint Set Of 10 Contains Ten Essential Student Quality Colours. Ideal For Uniform Coverage In A Vibrant, Opaque Matt Finish. Perfect For Students And Hobbyists. This Set Contains The Following Colours: Titanium White, Process Yellow, Cadmium Yellow Dee

Jackson's · £25.50

The Designers' Gouache line has been a studio standard for illustration for decades, which means its behaviour is well-documented and very consistent. It won't surprise you. The colour selection in the 10-piece set leans toward the range you'd need for illustration work, which means a little editing is useful before you take it outdoors: focus on the earthy landscape tones and set aside anything you won't reach for. A compact field palette of 6–8 colours is far more practical than trying to carry everything.

The same weather-sensitivity caveats apply here as with all traditional gouache. Winsor & Newton's ubiquity in UK retail is a genuine practical advantage: if you squeeze out the last of a colour while you're in the middle of a project, a replacement is rarely more than a day away.

Best for: Painters curious about traditional gouache outdoors who want a low-cost, widely available first set before committing to a larger palette.

How to Build a Portable Gouache Kit for UK Conditions

Getting the right paints is only half the job. How you assemble them into a field kit matters just as much, particularly in the UK, where the walk to a location might be long and the conditions when you arrive unpredictable.

The compact acrylic gouache kit (for exposed UK locations): Start with a 6–12 colour selection from either the Liquitex Essentials range or the Holbein Acryla school set. Decant colours into small wells in a folding travel palette rather than carrying bottles or tubes in full. Pair this with a mixed-media sketchbook (look for ones designed for wet media) or a small primed panel for a more rigid surface. The priority here is permanence and low weight. If a squall rolls in, your study survives. A good sketchbook for outdoor watercolour and gouache work is worth choosing carefully.

The traditional gouache value-study kit (for overcast light and sheltered spots): An 8–10 colour selection from Holbein Artists' Gouache or the Winsor & Newton set, weighted toward the earth colours and muted neutrals that suit UK landscape light. Carry 300 gsm watercolour paper in a rigid portfolio or sketchbook to prevent buckling when you rewet passages. A small misting bottle helps keep paint on the palette workable on dry or windy days. Most importantly, carry a flat, protective folder for finished studies so they aren't disturbed on the journey home.

The hybrid approach: Some painters use acrylic gouache for large colour blocks and initial structure, then work traditional gouache on top for nuanced details and soft edges. It can work well, but test your specific paints together at home before relying on this system outdoors. Adhesion and lifting behaviour can vary between brands, and discovering a problem mid-painting on a hillside is not the moment you want it.

Common Questions About Gouache Outdoors

Paint drying too fast in wind is the most common frustration with gouache outdoors. The fix is practical: work smaller, use deeper palette wells rather than a flat surface, and mist lightly if needed. Acrylic gouache in particular sets quickly in a breeze, so mix what you need and apply it promptly.

Colour shift on drying catches many painters off guard. Gouache tends to dry slightly lighter than it appears wet, particularly in darker tones and high-chroma colours. Making a quick swatch chart of your palette before you start gives you a reliable reference and takes only a few minutes.

Rain is the serious concern. Acrylic gouache is much safer once the paint film has cured (allow at least 20 minutes in normal outdoor conditions); a light shower won't damage it. Traditional gouache remains vulnerable indefinitely. If the forecast looks uncertain, acrylic gouache is the sensible call.

Kit weight is worth thinking about from the start. A full set of tubes adds up quickly. A curated six-colour palette, decanted into a compact folding palette, is usually enough for a focused outdoor study and keeps your bag manageable on longer walks.

Our Verdict — The Best Gouache for Plein Air in the UK

For most UK plein air painters, the top pick is Liquitex Professional Acrylic Gouache. It's permanent, reliably matte, broadly available through Jackson's Art and other UK suppliers, and the individual bottle format makes restocking specific colours straightforward. It suits the reality of painting outdoors in Britain: conditions change, and a paint that survives them without fuss is worth its price.

If you want the rewetting quality and atmospheric handling of traditional gouache, Holbein Artists' Gouache is the one to reach for. It's a professional product that rewards careful, considered outdoor work in sheltered conditions, and the individual tube availability in the UK makes palette-building over time genuinely practical.

For those just starting out, the Winsor & Newton Gouache Set of 10 is the easiest and most accessible entry point, particularly if you have a Cass Art nearby. The Holbein Acryla school set runs it close for anyone who wants to start with acrylic gouache: the colour quality belies the entry-level price, and the permanence is a genuine outdoor advantage from day one.

Golden SoFlat Matte Acrylic is worth knowing about as a peripheral option for painters who want maximum paint film permanence on primed panels, though it behaves more like a matte acrylic than gouache in the traditional sense.

Whichever product you start with, a compact, curated palette and an understanding of what your chosen gouache type will and won't do outdoors will serve you far better than carrying the largest set you can find.
