Most grey pigments have a cool or warm cast to them, as the human eye can detect even a minute amount of saturation. Yellow, orange, and red create a "warm grey". Green, blue, and violet create a "cool grey". When there is no cast at all, it is referred to as "neutral grey", "achromatic grey" or simply "grey".
