The color moves from the sky to mood, and from mood to whole stretches of time. Daniel C. Gerould's Witkiewicz collection, The Beelzebub Sonata (1980), has "the era of gray, boring banality and stagnation," where gray keeps company with words for monotony. Bleak, its near neighbor, suggests harshness; gray suggests sameness, an absence of color rather than its cruelty.

It names a kind of being rather than a shade, so only context separates it from the color word. It belongs chiefly to American UFO writing, where it sits alongside the full phrase grey alien that it shortens.
