Hydron colours on cotton piece-goods
A trade sample book issued in New York in 1900 by the Cassella Color Company, showing cotton piece-goods dyed with its Hydron dye pastes for textile buyers and dyers. Its pages are grids of numbered rectangular swatches, each labelled with a dye name and paste strength, in shades of blue, violet, brown, and yellow. A designer can use them as a reference for period dye colours, muted fabric tones, and the plain swatch-card layout.
