A one-page encyclopedia entry on the color red in dyeing, from Rees's Cyclopedia. It lists the seven recognized casts of red (scarlet, crimson, madder, half-grain, half-crimson, orange-red, cochineal scarlet) and reduces them to three principal dyestuffs: kermes, cochineal and madder. It gives the mordants and additives used for each, mentions the discouraged Brasil red, and lists the shades available within each cast.
