Grey (US: gray) is an achromatic or neutral color.
Complementary colors are defined to mix to grey, either additively or subtractively, and many color models place complements opposite each other in a color wheel. To produce grey in RGB displays, the R, G, and B primary light sources are combined in proportions equal to that of the white point. In four-color printing, greys are produced either by the black channel, or by an approximately equal combination of CMY primaries. Images which consist wholly of neutral colors are called monochrome, black-and-white or greyscale.
The first recorded use of grey as a color name in the English language was in AD 700. Grey is the British spelling, whereas gray is the American spelling, though the latter was also in common usage in the UK until the second half of the 20th century, and the former is considered acceptable by most American dictionaries and is commonly seen in usage, e.g. in the Grateful Dead hit Touch of Grey.
Two colors are called complementary colors if grey is produced when they are combined additively. Grey is its own complement.

;Gerontology The color grey is often associated with aging or the passage of time, likely due in part to the decreased pigment-production of hair follicles over time, corresponding to the greying of human hair. In this context, grey is often used synonymously with "elderly", as in "the grey pound" or "grey power" (when referring to the economic or social influence of the elderly), or as used by groups such as the Gray Panthers.
;Nanotechnology Grey goo is a hypothetical end of civilization scenario, involving molecular nanotechnology in which out-of-control self-replicating robots consume all living matter on Earth while building more of themselves (a scenario known as ecophagy).
;Politics Martin Bormann was called the grey eminence because, as the executive secretary to Adolf Hitler, he amassed great power behind the scene, because he was the one who controlled access to the Führer. The National Renaissance Party was an American neo-fascist group led by James Hartung Madole. The party was active from 1949 to 1979. The members of the party were also known as the gray shirts.
;Sexuality In the bandana code of the gay leather subculture, wearing a grey bandana means that one is into the fetish of bondage. In gay slang, a grey queen is a gay person who works for the financial services industry (this term originates from the fact that in the 1950s, people who worked in this profession often wore grey flannel suits).

;Symbolic language In France, to be "grey" (être gris) means to be drunk. Accordingly, to be extremely drunk is to be "black" (être noir). In the U.S., the college slang verb to gray was used around 1900 to mean to get drunk.
