Setamine colors : for tin-weighte silk
A 1927 trade colour card from E.I. du Pont de Nemours & Company of Wilmington, Delaware, issued to show dye shades for tin-weighted silk to dyers and textile buyers. Its pages are plain grids of rectangular swatches, each row labelled with a dye name and graded strengths in percentages, which a designer could use as a reference for a systematic colour scale.
