Crimson

Derived from English crimson, the name for a strong, bright, deep purplish-red color. The English word is ultimately derived from Arabic qirmiz. It is originally the color of the dye produced from a scale insect, Kermes vermilio, but the name is now also used as a generic term for those slightly bluish-red colors that are between red and rose.

As a given name, Crimson has been in use since the late 1800s.
