Dyeings fast to milling of anthracene chrome and anthracene chromate colours on loose wool
A trade sample card from 1900 issued by the Cassella Color Company of New York, showing dyed wool swatches to demonstrate fastness to milling for textile dyers and manufacturers. The pictures are strips of dyed wool in rows of black, navy, green, teal, gold, orange, brown and red, each labelled with a dye name and number, so a designer could use them for a palette of muted, heavy textile tones.
