Crimson
Crimson is a strong, red color, inclining to purple. It originally meant the color of the kermes dye produced from a scale insect, Kermes vermilio, but the name is now sometimes also used as a generic term for slightly bluish-red colors that are between black and rose.
Maroon
Maroon (US & UK mə-ROON, Australia mə-ROHN) is a dark brownish red color which takes its name from the French word marron, or chestnut.
The Oxford English Dictionary describes it as “a brownish crimson or claret color.”
In the RGB model used to create colors on computer screens and televisions, maroon is created by turning down the brightness of pure red to about one half. Maroon is the complement of teal.
