A natural dye that was historically made into paints. Lac Lake is made from Coccus lacca insects (distinct from Kermes and Cochineal). Lac Dye is said to be lightfast, but we would take that rather contextually in the conversation about natural reds which are not as lightfast on the whole as one would wish. Kremer mentions its use in watercolor and oil. An excellent discussion of the history of this pigment can be found at Kremer Pigments here
