Sumi palette
Willow Brook
Dark anchor, working middle, light release: #ae2d1b, #db5f4b, #fb7c66, #ff9582, #ffc3b7 form a tetradic sumi set with somewhere to stand at every lightness. Made for wellness apps where the interface must feel calm, not clinical. The darkest and lightest stops clear AA for large text.
