Livid is a medium bluish-gray color. This color name comes from the Latin color term lividus meaning "'a dull leaden-blue color', and also used to describe the color of contused flesh, leading to the English expression 'black and blue'".^[1] The first recorded use of livid as a color name in English was in 1622.^[2]

There is a range of colors called livid colors that combine the colors blue and gray. Some of these colors are shown below.

Livid (blue-gray) is the opposite concept from brown. Brown colors are mainly dark orange and dark red colors—warm colors on the warm color side of the color wheel, while blue-gray (livid) colors are mainly dark blue and dark azure colors—colors on the opposite side of the color wheel—cool colors on the cool color side of the color wheel.

Alternate names are blue-gray (American English) or blue-grey (British English), which was a name introduced by Crayola for a crayon color used from 1958 to 1990. Thus, the normalized color coordinates for livid and blue-gray are identical.
