How it works
Gouache painting ideas work best as flat, opaque shapes, so these 84 are fruit still lifes, house and shop fronts, poster landscapes, food illustrations and patterned interiors. Each lists its colours from the ground up and one step.

Why flat shapes and patterns suit gouache
Gouache is pigment, water and a binder, usually gum arabic, made to be opaque. That lets a light colour sit on a dark one. Blood orange slices on navy starts with the navy, and Mustard armchair against striped wallpaper paints the chair straight over the stripes. 39 of the 84 steps wait for a layer to dry first.
Five-colour posters and colours that shift as they dry
Gouache was long a working paint for posters and illustration, and the 17 five-colour poster landscapes borrow that look: five colours each and no blending. Pale mixes tend to dry a little darker and dark mixes a little lighter, so a colour is hard to match later. Mix all five before you start, as Mountain lake in five flat blues says.
- Under More filters, Level holds 24 easy first gouache subjects, such as Halved papaya with black seeds.
- Dry gouache can be rewetted, so lay each top layer in one pass and never scrub the colour below.
- Save one colour for one shape: Fjord with one red cabin keeps its red for last.
Questions and answers
What is the difference between gouache and watercolour?
Gouache is made like watercolour but more opaque: its pigment particles are typically larger, there is far more pigment to binder, and a white filler such as chalk may be added. Watercolour lets the paper show; gouache covers it and dries matte.
Do these ideas need acrylic gouache?
No. Every idea works in traditional gouache, which is bound with gum arabic and can be rewetted. Acrylic gouache dries water-resistant, so a dry layer will not lift under the next. That helps on pattern-heavy ideas such as Bed with a patchwork quilt.
Which gouache colours should I buy first?
Cream is in 48 of the 84 palettes, a green in 38, white in 33 and a red in 30. Cream mixes from white and a touch of ochre, so start with a big white, a red, a green, navy, ochre and black.
