Etymology

Origin of crimson

First recorded in 1375–1425; late Middle English cremesin, cremesie, crensein, crim(e)sin, from Medieval Latin cremesīnus, ultimately from Arabic qirmizī, equivalent to qirmiz + a suffix indicating relationship or origin; see origin at kermes; see also carmine, cramoisy

Explanation

Crimson is a deep, vivid shade of red. You could describe flowers, blood, or blushing cheeks as crimson. The ruby red color crimson shows up brilliantly in nature, in the form of flowers, birds, and insects. In fact, it was an insect that led to the word crimson in the first place; an insect called kermes was used for centuries to make a deep red dye, which was called cremesin in Old Spanish and eventually became crimson.
