Sumi palette
Iris Bookshop
A quiet five-stop sumi arc with a confident middle — #892500 carries the weight and #fc9f83 carries the air, with #b75133, #d66d4e and #dd8368 bridging in split-complementary formation. Built for dashboards where status colors must survive color-vision differences. The darkest and lightest stops clear AA for large text.
