Water Based Paints Price Comparison 2026
Compare 157 water based paints from Winsor & Newton, Royal Talens and Van Gogh. Find the best price across top UK retailers.
Water-based paints occupy a fascinating middle ground in the art materials world — they're simultaneously the most accessible medium for beginners and the most technically nuanced for professionals. Our catalogue of 157 products spans everything from Crayola washable bottles for the kitchen table to Winsor & Newton professional gouache sets, with prices running from 0 £ to 0 £. The spread tells a story: most of the market clusters tightly around the median, which means the jump from student to artist grade is less dramatic here than in, say, oil paints.
Winsor & Newton dominates this category with 86 products — more than half the entire catalogue — and their average price sits comfortably below that of Van Gogh, which positions itself firmly in the upper-mid tier. Royal Talens, the Dutch parent company behind Van Gogh, rounds out the top three with 39 listings. What's worth noting is that "water-based paint" covers genuinely different formulations: gum arabic-bound watercolours behave nothing like acrylic polymer emulsions, and textile-specific paints are a different beast again. Buying the wrong type for your substrate is the most common — and most avoidable — mistake we see.
Lightfastness is the criterion that separates a lasting piece from one that fades within a few years. Professional ranges from Winsor & Newton and acrylic paint lines from Royal Talens typically carry ASTM I–II ratings, whilst budget sets rarely publish this data at all — which is itself a red flag. For anyone working on pieces intended to last, that rating matters far more than the price per tube. For classroom use or craft projects, it's largely irrelevant.
Gouache deserves a special mention. It's technically a water-based paint but behaves very differently from watercolour: fully opaque, fast-drying, and ideal for illustration and design work. Winsor & Newton's Designers Gouache range is well represented here and remains a benchmark for the medium. If you're comparing options across acrylic paints or even painting accessories, it's worth deciding on your medium first — the right brush or substrate makes as much difference as the paint itself.
Prices across UK retailers vary more than you'd expect on identical products, particularly on the multi-set formats. Checking offers before buying is straightforward here — the difference between the cheapest and most expensive listing for the same Winsor & Newton set can be significant, especially around Black Friday and the January sales when art supply retailers tend to discount heavily.
How to Choose the Right Water-Based Paint
With 157 products across wildly different formulations — from children's washable bottles to professional artist gouache — picking the right water-based paint is less about brand loyalty and more about matching the medium to your actual use case. Here's what genuinely matters.
Formulation type: watercolour, gouache, or textile?
This is the first decision, and it's non-negotiable. Watercolours (gum arabic binder) are transparent and rewettable — ideal for paper, washes, and layered glazing techniques. Gouache is opaque and fast-drying, preferred by illustrators and designers who need flat, bold colour. Textile paints use a flexible binder that bonds to fabric fibres without cracking — using a standard watercolour on fabric will simply wash out. Getting this wrong means starting over, so identify your substrate before anything else.
Pigment grade: student vs. artist
Student-grade paints use lower pigment loads and sometimes substitute cheaper synthetic pigments for expensive ones (cadmium, cobalt). The result is less saturated colour that requires more layers to achieve depth. Artist-grade paints — Winsor & Newton Professional, Van Gogh — carry higher pigment concentrations and publish individual pigment codes (e.g. PB29, PY150) on the tube. If you see only a colour name and no pigment code, that's a student product at best. For learning and experimentation, student grade is perfectly fine and considerably cheaper. For finished work, the upgrade is worth it.
Lightfastness rating (ASTM I–II for anything permanent)
Lightfastness measures how resistant a pigment is to fading under light exposure. ASTM I (Excellent) and ASTM II (Very Good) are the benchmarks for archival work — anything rated III or below will visibly fade within years, not decades. Professional ranges from Winsor & Newton and Royal Talens publish ASTM ratings per colour; budget sets and children's products typically don't. If you're creating work to sell, exhibit, or frame, this rating is the single most important technical criterion. For sketchbooks and practice, it's irrelevant.
Packaging format relative to your working scale
Tubes (5–15 ml) give precise colour control and suit portable or studio work. Half-pans and full pans are compact and travel-friendly, ideal for plein air painting. Bottles (250–500 ml) are economical for large-scale projects, murals, or textile work — the Creativ Company Textile Color 500 ml bottle is a good example of this format done well. The cost-per-millilitre difference between a 14 ml tube and a 500 ml bottle of the same colour can be dramatic, so match the format to your actual consumption.
Safety certification for children's use
For products used by children, ACMI AP (non-toxic) certification and EN 71-3 compliance are the minimum requirements. Crayola's washable range carries these certifications and is specifically formulated to wash out of clothes and off skin — a genuine practical consideration. Don't assume that "water-based" automatically means safe for children; some professional pigments (cadmium, manganese) carry health warnings even in water-based form. Check the label, not just the medium.
Rewetting properties for extended working time
Gum arabic-based watercolours are fully rewettable — dried paint on the palette can be reactivated with a damp brush, which is enormously practical. Acrylic-based water paints dry to a water-resistant film and cannot be rewetted once cured. If you work slowly, take breaks, or frequently return to a palette, this distinction matters. Gouache sits in between: it rewets partially but can become muddy if overworked. Winsor & Newton's Cotman range (gum arabic) and their Designers Gouache behave very differently in this respect despite both being "water-based".
- Entry-level and children's (From 0 £ to 0 £) : Washable children's paints (Crayola), individual Van Gogh tubes, and basic single-colour bottles. Fine for classrooms, craft projects, and young artists. Don't expect published lightfastness ratings or high pigment loads — that's not what these are for.
- The sweet spot for hobbyists (From 0 £ to 0 £) : Multi-set student ranges from Primo and Van Gogh, plus individual Winsor & Newton Cotman tubes. Good pigment quality for the price, suitable for regular practice and semi-serious work. Most buyers will find everything they need here.
- Serious amateur and semi-professional (From 0 £ to 0 £) : Van Gogh sets, Winsor & Newton Cotman collections, and Creativ Company multi-palettes. Better pigment concentration, more reliable lightfastness data, and broader colour ranges. The right tier for anyone producing finished work.
- Professional and artist grade (Over 0 £) : Winsor & Newton Professional, Caran d'Ache, Faber-Castell, and large-format sets. ASTM I–II lightfastness across the range, single-pigment formulations, and maximum pigment load. Caran d'Ache in particular commands a premium that's justified for archival and exhibition work. Not necessary for most buyers, but the difference is real.
Top products
- Winsor & Newton COTMAN WATER COLOURS (Winsor & Newton) : The Cotman range is the go-to recommendation for serious beginners and hobbyists — reliable pigment quality, gum arabic binder for proper rewetting, and widely stocked across UK art retailers. Not artist grade, but honest about what it is.
- Van Gogh 20820110 water based paint Blue, Grey, White, Yellow 10 ml Tube 10 pc(s) (Van Gogh) : A well-curated 10-tube set that covers the essential mixing palette without unnecessary filler colours. Van Gogh sits a notch above Cotman in pigment concentration — a good upgrade for anyone who's outgrown student grade.
- Winsor & Newton Designers Gouache Introductory water based paint Black, Blue, Green, Red, White, Yellow 14 ml Tube 10 pc(s) (Winsor & Newton) : The definitive introductory gouache set — opaque, fast-drying, and the industry standard for illustration and design work. The 14 ml tubes are generous for the price. Worth noting: gouache behaves nothing like watercolour, so don't buy this expecting transparent washes.
- Crayola 10 Washable paint bottles (Crayola) : The only genuinely child-safe option in this top 15 — EN 71-3 compliant, actually washable from clothes and skin, and priced accessibly. Not for serious art work, but exactly right for its intended audience.
- Creativ Company Art Aqua watercolour paints water based paint Multi Palette 48 pc(s) (Creativ Company) : 48 colours sounds impressive, but large palettes like this often contain redundant hues with inconsistent pigment quality across the range. Good for craft and mixed-media projects where colour variety matters more than archival quality — less convincing as a serious watercolour set.

Frequently Asked Questions
What is the difference between watercolour and gouache?
Watercolour is transparent and rewettable, whilst gouache is opaque and dries to a matte, chalky finish. Both are water-based and use similar binders, but gouache contains a higher pigment load and often chalk or blanc fixe to achieve opacity. In practice, watercolour suits washes, glazing, and luminous effects on paper; gouache is preferred for illustration, flat colour work, and any application where you need to paint light colours over dark ones — something watercolour cannot do.
Can I use water-based paint on fabric?
Only if the product is specifically formulated for textiles. Standard watercolours and gouache will wash out of fabric because their binders aren't designed to bond with fibres. Textile-specific water-based paints — like the Creativ Company Textile Color range — use flexible acrylic or synthetic binders that cure into the fabric, typically after heat-setting with an iron. Using the wrong product means the colour disappears in the first wash.
Is student-grade paint worth buying, or should I go straight to artist grade?
Student grade is absolutely worth buying if you're learning or experimenting — the lower price point lets you use paint freely without anxiety, which is genuinely important for developing technique. The trade-off is lower pigment concentration, occasional hue substitutions, and rarely published lightfastness data. Once you're producing work you want to keep or sell, moving to artist grade (Winsor & Newton Professional, Van Gogh) makes a noticeable difference in colour saturation and permanence. Many working artists use student grade for studies and artist grade for final pieces.
What does lightfastness mean, and does it actually matter?
Lightfastness is the resistance of a pigment to fading when exposed to light over time, rated on the ASTM scale from I (Excellent) to V (Very Poor). It matters enormously for finished artwork — a painting made with ASTM III or lower pigments can show visible fading within a few years of display. For sketchbooks, practice work, or anything not intended for long-term display, it's largely irrelevant. Professional ranges from Winsor & Newton and Royal Talens publish ASTM ratings per colour; if a product doesn't list this information, assume it's not archival.
Are expensive water-based paints actually better, or is it just branding?
The price difference is real, but only up to a point. The jump from budget to mid-range (around 0 £) delivers genuine improvements in pigment concentration and colour consistency. The jump from mid-range to premium (over 0 £) is more nuanced — you're paying for single-pigment formulations, ASTM I lightfastness, and finer particle sizes that affect wash smoothness. Caran d'Ache, for example, commands a significant premium that's justified for professional archival work but overkill for most hobbyists. Beyond a certain price, you're paying for marginal gains that most artists won't notice in practice.
What pitfalls should I avoid when buying water-based paint sets online?
The biggest trap is buying a large set of colours you don't need instead of fewer, higher-quality tubes. A 48-colour student set often contains redundant hues and low-pigment formulations that frustrate more than they help. Also watch for products listed as "water-based" without specifying the formulation — watercolour, gouache, acrylic, and textile paint are all technically water-based but behave completely differently. Finally, check whether the set includes a colour chart with pigment codes; if it doesn't, the manufacturer is hiding the fact that multiple colours share the same cheap pigment base.
Which water-based paint brands are best for beginners in 2026?
Winsor & Newton's Cotman range remains the benchmark for beginner watercolours — reliable quality, widely available from UK retailers like Cass Art and Hobbycraft, and well within the mid-range price bracket. For gouache, their Designers Gouache Introductory set is a solid starting point. Van Gogh is a step up in pigment quality and suits anyone who's moved past the absolute basics. For children specifically, Crayola's washable range is the safest and most practical choice, with EN 71-3 compliance and genuinely effective washability.
