Chrome colours for wool
A 1910 dye sample book from the Cassella Color Company of New York, issued for textile dyers and wool processors. Its pages show swatches of chrome and acid wool dyes, each dyed at 2% and 4% strength and labelled with its trade name and dyeing method. A designer might take from these the range of deep browns, blues and maroons that dyed wool can reach, and the clean grid of paired swatches as a model for presenting colour comparisons.
