carmin de cochenille

Note d'application

• (fr-FR) pigment laqué rouge obtenu à partir d'un colorant rouge tiré de différentes espèces de cochenilles, originaires d'Amérique centrale (voir cochenille)
• (en-US) A generic name for two closely related organic red lakes that are obtained from scale insects, cochineal and kermes. Neither pigment is permanent enough for use in fine art because they discolor in sunlight. They were replaced first by madder and alizarin, then later by synthetic organic red colors.
