Grey or 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, Canadian, Australian, Irish, New Zealand and South African spelling, although gray remained in common usage in the UK until the second half of the 20th century. Gray is the preferred American spelling, although grey is an accepted variant. Gray became the preferred spelling in American English around 1825.
Famous quotes containing the word grey:
“Indeed, my mothers beautiful face still shone with youthfulness that night when she so softly held my hands and sought to stop my tears; but, precisely, it seemed to me that this should not have happened, her anger would have saddened me less than this new sweetness that my childhood had never known; it seemed to me that, with a hidden and impious hand, I had just traced the first wrinkle and made appear the first grey hair in her soul.”
—Marcel Proust (18711922)
“There is grey in your hair.
Young men no longer suddenly catch their breath
When you are passing;
But maybe some old gaffer mutters a blessing
Because it was your prayer
Recovered him upon the bed of death.”
—William Butler Yeats (18651939)
“Each had his past shut in him like the leaves of a book known to him by heart; and his friends could only read the title, James Spalding, or Charles Budgeon, and the passengers going the opposite way could read nothing at allsave a man with a red moustache, a young man in grey smoking a pipe.”
—Virginia Woolf (18821941)
