Today’s color idea is: FRENCH VERMILION by Sennelier.
“The word vermilion came from the Old French word vermeillon, which was derived from vermeil, from the Latin vermiculus, the diminutive of the Latin word vermis, or worm. The name originated because it had a similar color to the natural red dye made from an insect, the Kermes vermilio, which was widely used in Europe. The term cinnabar was used interchangeably with vermilion until the 17th century, when vermilion became the more common name. By the late 18th century ‘cinnabar’ applied to the unground natural mineral only.”
