The cool winter colour palette is built from bright, blue-based shades: magenta, sapphire, turquoise, violet, scarlet and snow. These are saturated cool colours at full intensity, sitting at the maximum coolness of -1.00 with a chroma of 0.70 that keeps them vivid and clear.
Colouring in this season is unmistakably blue-based and clearly contrasted: cool-toned skin, hair from ash brown to soft black, and eyes in cool blue, grey or cool brown. It shares its full coolness with Cool Summer. Chroma separates them: 0.70 here, meaning clear and bright, against -0.60 there, meaning softened. Same temperature, opposite brightness, and it is the pair most often mixed up. The same season is written as the cool winter color palette in American spelling.
