Kermes is one of the oldest dyes known, being mentioned in the Bible book of Genesis (38:28) as scarlet or crimson. It is obtained from the bodies of an insect, Kermes ilices (formerly known as Coccus ilicis). It is chemically very similar to carmine and, as the older name indicates, the insects are related to those from which carmine is obtained. Although it forms bright crimson lakes, it is not used in histotechnology.
