Gouache
Gouache is watercolour that decided to stop being transparent. Same binder, same pigments, same water — but with the addition of chalk or other opaque fillers, it becomes a medium that covers completely and dries to a flat, velvety matte surface unlike anything else in painting.
The flatness is not a limitation. It is the point. Gouache does not mimic light the way oil or watercolour does — it describes it. Every shape is a decision. Every edge is deliberate. The medium demands clarity of thought because there is nowhere to hide: no texture, no gloss, no translucency to carry you through an uncertain passage.
Historically the medium of illustration, animation, and design, gouache is now experiencing a serious reconsideration as a fine art medium. Its opacity makes it the only water-based paint that works on toned or dark surfaces. Its fast drying and rewettable surface make it ideal for quick, direct colour work. And its matte finish photographs and reproduces better than almost any other medium — which in a visual culture driven by screens is not a trivial advantage.

Properties ▾
Binder: Gum arabic, same as watercolour.
Opacity: Opaque to semi-opaque. The opacity comes from chalk, blanc fixe, or precipitated chalk added to the pigment-gum mixture.
Drying time: Fast — 5 to 20 minutes. Faster than watercolour because the chalk absorbs moisture quickly.
Finish: Flat, velvety matte. No gloss whatsoever when dry.
Re-wettable: Yes. Dried gouache reactivates with water, which makes corrections possible but later layers risky — wet paint can lift what is beneath.
Colour shift: Gouache shifts significantly from wet to dry — darks lighten, lights darken. This is the medium's most demanding characteristic and takes time to learn.
Surfaces: Watercolour paper, illustration board, toned paper, black paper, card. Works on surfaces that defeat transparent watercolour.
Lightfastness: Varies by pigment, same as watercolour. Always check ASTM ratings. Artist-grade gouache uses the same high-grade pigments as artist-grade watercolour.
Mixability: Gouache mixes cleanly and predictably. Because it is opaque, mixed colours are true — what you see on the palette is what you get on the paper.
Techniques ▾
Flat wash
Mix a generous quantity of paint to a consistent creamy consistency — not too thick, not too thin — and apply in single, confident strokes. Do not go back into a drying passage. Gouache dries fast and reworking a drying edge creates streaks that cannot be fixed without repainting the entire area.
Layering: Allow each layer to dry completely before applying the next. Wet paint will reactivate what is beneath and the colours will mix unintentionally. Thin the upper layers slightly more than the lower ones — too much water and the underlayer lifts; too little and brushstrokes show.
Working on toned paper: Gouache is the only water-based medium that works effectively on mid-toned or dark paper. Start with your mid-tones, build darks with thin transparent layers, and reserve your opaque white and light mixtures for final highlights. The toned paper does the work of establishing the overall value structure.
Colour mixing: Because gouache is opaque, colour mixing is additive and predictable. Mix your colours fully on the palette before applying — partial mixes create streaky, unpredictable results on paper. Add white to lighten rather than water, which weakens the opacity.
Dry brush on gouache: Unlike watercolour, gouache supports dry brush work on smooth surfaces as well as textured ones. The opacity means broken marks read as texture rather than transparency, which is a completely different visual effect.
Corrections: Let the error dry completely, then paint over it with opaque colour. Gouache covers its own mistakes better than any other water-based medium — this is one of its greatest practical advantages.

Gouache will teach you to commit. Every mark is final until you decide to paint over it — and that is not a problem, that is the discipline.
History ▾
c. 1400s — Gouache technique first appears in European manuscript illumination, used for opaque highlights and corrections over transparent watercolour base layers.
1500s
The medium becomes standard practice for preparatory studies and cartoons in European workshops. Raphael and his contemporaries use gouache for detailed compositional studies.
1600s
1700s — Gouache becomes the preferred medium for topographical painters and veduta artists across Europe. Its opacity and portability make it ideal for working outdoors and reproducing architectural detail.
1800s
The rise of illustrated press and publishing creates enormous demand for gouache illustration. It becomes the workhorse medium of commercial art worldwide.
1900s
Animation studios including Disney adopt gouache as the standard medium for production cel painting. Every frame of Snow White, Fantasia, and Pinocchio is painted in gouache.
1950s
1980s — Gouache dominates graphic design, advertising illustration, and editorial art before digital tools replace it commercially.
1990s
Digital design nearly eliminates gouache from commercial practice. The medium retreats into fine art, where a small community of serious practitioners keeps it alive.
2015 onwards — A significant revival begins, driven partly by artists seeking alternatives to screens and partly by the influence of Japanese watercolour and gouache practice gaining international visibility. Designers and illustrators rediscover the medium on its own terms.
Brands ▾
Professional / Artist Grade
Holbein Artists Gouache
Japanese. Holbein gouache is the benchmark for professional gouache worldwide. Exceptionally consistent colour-to-colour, very high pigment load, and a matte finish that is genuinely velvety rather than chalky. Their range of over 100 colours includes some of the most useful neutrals and earth tones available in any gouache line. The standard against which others are measured.

Schmincke Horadam Gouache
German. Schmincke brings the same obsessive pigment quality from their watercolour line to their gouache. Exceptionally opaque, intensely pigmented, and with the characteristic Schmincke consistency that feels expensive the moment you open the tube. Their Designer Gouache line is slightly more fluid and designed specifically for flat graphic work.

Sennelier Extra-Fine Gouache
French. Sennelier adds honey to their gouache formula as they do with their watercolour — the result is a paint that stays workable longer and has an unusually smooth, creamy consistency. Particularly good for wet blending and soft-edged work. Their colour range includes some unusual historical pigments not found in other gouache lines.

M. Graham Gouache
American. M. Graham uses blackcurrant honey as a humectant instead of the synthetic additives used by most brands. The paint stays moist in the tube for years and on the palette indefinitely. Exceptionally rewettable. The colour range is smaller than Holbein or Schmincke but every colour is a single pigment — mixing is clean and predictable.

Mid Range
Winsor & Newton Designers Gouache
British. The most widely available professional-level gouache worldwide. Consistent, reliable, and with a comprehensive colour range.
