Sumi palette
Maroon Bookshop
A quiet five-stop sumi arc with a confident middle — #ba1003 carries the weight and #ffc4b9 carries the air, with #e85240, #ff7966 and #ff9685 bridging in tetradic formation. Built for dashboards where status colors must survive color-vision differences. The darkest and lightest stops clear AA for large text.
