Warm Autumn scores the maximum 1.00 on temperature, making it one of only two seasons that is fully warm. Colouring is golden and rich: skin with a golden or bronze cast, hair from auburn through copper to warm chestnut, and eyes in warm hazel, amber or golden brown.
Chroma sits at -0.70, meaning colours are muted rather than clear. That is the axis separating it from Warm Spring, which shares the identical temperature but needs bright, fresh colour. Same warmth, opposite brightness.
