"Gray denotes a class of cool cinereous colours...The grays, like the other semi-neutrals, are sober, modest colours, contributing to the expression of gloom, sadness, frigidity, and fear,—the grave, the obscure, the spectral,—age, decrepitude, and death; bordering in these respects upon the powers of black, but aiding the livelier and more cheering expressions of other colours by diversity, connexion, and contrast, and partaking of the more tender and delicate influence belonging to white, as they approach it in their lighter tints."
