Sumi palette
Perennial Canyon
A quiet five-stop sumi arc with a confident middle — #721e00 carries the weight and #f68766 carries the air, with #b13400, #d0522a and #d76b4b bridging in triadic formation. Built for dashboards where status colors must survive color-vision differences. The darkest and lightest stops clear AA as a text pair.
