Sumi palette
Sooty Foundry
A quiet five-stop sumi arc with a confident middle — #a21e08 carries the weight and #ffb1a1 carries the air, with #cf533e, #ef7059 and #f58873 bridging in triadic formation. Built for hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
