Colour : a text-book of modern chromatics with applications to art and industry
Ogden N. Rood's 1904 London textbook Colour, a scientific treatise on modern chromatics aimed at readers of art and industry, published by Kegan Paul, Trench, Trübner. Its diagrams are plain line drawings explaining colour mixing, the Dichroscope, and the spectrum, with a prism splitting white light into labelled bands from red through violet, useful to a designer studying how hues are built and separated.
