Color and its applications
A 1921 technical treatise on color by Matthew Luckiesh, published in New York by D. Van Nostrand Company, aimed at students and practitioners of color science. The pictures are plain scientific diagrams and photographs: a light-intensity graph labelled in lux, a colour-to-note chart with a keyboard-style instrument, and a portable spectrophotometer on a tripod. A designer might take from them the clean, measured look of early laboratory graphics, with grid paper, labelled curves and fine line drawings.
