Colour as a means of art : being an adaptation of the experience of professors to the practice of amateurs
Colour as a means of art is an 1849 London treatise by Frank Howard and Charles Joseph Hullmandel, published by Henry G. Bohn, written to guide amateur painters in the use of colour. The two pictures are loose watercolour studies: one of billowing red, black and blue washes at the edge of a pale sky, the other of a misty gorge with dark rock walls and a bright sky opening between them, showing how wet washes and bold contrasts of warm and cool build atmosphere and depth.
