Color standards and color nomenclature
A colour reference book by the American ornithologist Robert Ridgway, self-published in Washington, D.C. in 1912 for scientists and artists needing standard names for colours. Its plates are rows of labelled swatches arranged in grids of white, pinks, reds, oranges, yellows and browns, with each swatch set against a grey-tan page. A designer could take from them a systematic palette of named, graded tints and shades, useful for planning colour ranges or building a tonal scale.
