Halbwolle = Half-wool dyeing = La teinture de la mi-laine
A dye-sample book from 1900 published by the Farbenfabriken vorm. Friedrich Bayer & Co. at Leverkusen near Cologne, aimed at textile dyers working in wool and half-wool. Its pages are grids of small rectangular fabric swatches, each labelled with a dye code, showing how the same dye colours woven cloth. A designer could use the tight herringbone and twill textures and the rich dark palette of navy, black, maroon, and olive as reference for fabric colour and weave.
