Blue-gray (also blue-grey in British English) is a medium blue-gray color on the cool side of the color wheel. The name blue-gray was introduced by Crayola for a crayon color used from 1958 to 1990. The complementary color is #CC9966, a warm khaki or brown.

It has historically been called livid, from the Latin lividus, meaning "a dull leaden-blue color". The word entered English in the fifteenth century, first in medical use to describe the bluish-gray discoloration of bruised or damaged flesh, the condition also expressed in the phrase "black and blue". The familiar modern sense of livid meaning furiously angry developed later, via the intermediate sense of a face turning pale or ashen with rage.

There is a wide range of named blue-gray or livid shades, including steel blue, glaucous, cadet grey, and Payne's grey, among others. The color appears in nature, culture, and military uniform traditions around the world.
