The physical and physiological basis of color [electronic resource]
A late nineteenth-century scientific treatise on the physics and physiology of colour vision, published in Philadelphia in 1894 and drawn from the University College London library collection, aimed at students of optics and ophthalmology. The two pictures are plain photographic plates: a blurred banded striped field labelled Fig. 2, and a circular micrograph of retinal tissue with dense layered cell structure, printed sideways along the page edge. A designer might take their soft horizontal bands and microscopic textures as reference for abstract stripe or cellular patterns.
