Sumi palette
Coral Bazaar
A quiet five-stop sumi arc with a confident middle — #a41b00 carries the weight and #ffb2a2 carries the air, with #d54e36, #f56b52 and #fb856e bridging in tetradic formation. Built for hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
