The use of a box of colours, in a practical demonstration on composition, light and shade, and colour
A watercolour instruction manual by Harry Willson, published in London in 1842 by Tilt and Bogue for amateur painters learning composition, light and shade, and colour mixing. Plates pair tinted landscape studies — river banks, coastal shipping, wooded slopes — with grids of small monochrome sketches labelled by principle, offering loose washes, tonal diagrams and aged paper textures for layout and collage.
