Color-blindness [electronic resource] : its dangers and its detection

Jeffries, B. Joy (Benjamin Joy), 1833-1915 · 1879 · Boston : Houghton, Osgood ; London : Trübner · 5 pictures

A late nineteenth-century medical treatise by the American ophthalmologist B. Joy Jeffries, published in Boston and London in 1879, written to explain colour blindness and how to test for it. Its pictures are plain scientific diagrams: spectral-curve graphs with labelled colour bands, and branching family-tree charts and tables set on rotated printed pages. A designer could take from them a restrained, legible approach to diagrammatic charts, with dotted connector lines, letter labels and thin curved rules.
