Colour, in dying.

Encyclopedia Britannica, ensimmäinen painos, 1771

There are, in the art of dying, five colours, called simple, primary, or mother colours, from the mixture of which all other colours are formed: these are blue, yellow, brown, red, and black. Of these colours, variously mixed and combined, they form the following colours, pansy, blue, and red; from the mixture of blue and scarlet are formed amaranth, violet, and pansy; from the same mixture of blue, crimson, and red, are formed the columbine, or dove-colour, purple-crimson, amaranth, pansy, and crimson-violet. See BOTANY, Vol. I. p. 633.

Here it is to be observed, that they give the name crimson to all colours made with cochineal.
