Color and its applications
A 1921 colour science textbook by Matthew Luckiesh, published in New York by D. Van Nostrand, aimed at students and practitioners of colour. Its pictures are plain technical graphs of relative light value and brightness against wavelength or flicker frequency, plus a schematic optical diagram of a prism and lens arrangement; a designer might take their clean axis-and-curve layouts and restrained line styling as a model for data graphics.
