Grey

Grey is a color that is an intermediate between black and white. It is a neutral or achromatic color, meaning literally that it is a color "without color." It is the color of a cloud-covered sky, of ash and of lead.

Etymology and spelling

The first recorded use of grey as a color name in the English language was in AD 700. Grey is the dominant spelling in European and Commonwealth English, although gray remained in common usage in the UK until the second half of the 20th century. Gray has been the preferred American spelling since approximately 1825, although grey is an accepted variant.

In nature and culture

Grey is often associated with the elderly and wisdom, as in the grey hair of old age. It is a color seen widely in nature in both flora and fauna.

In science and technology

In the RGB color model used in computer and television screens, grey is produced by equal intensities of red, green, and blue light. In print media, grey is produced either by using black and white in a halftone technique, or by using equal amounts of cyan, magenta and yellow, most commonly associated with the CMYK color model.
