High Quality Content by WIKIPEDIA articles! Grey describes the colors ranging from black to white. These, including white and black, are known as achromatic colors or neutral colors. These "new" neutrals have low colorfulness and chroma. 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.
