Grey is an alternate spelling for the word gray, which is a color derived from mixing white and black. The word has also come to stand in for other mixtures as well.
"Gray" and "grey" are both correct spellings of the word for the neutral or achromatic color—a color “without color" between black and white, like a cloud-covered sky, ashes, or lead.
