Sumi palette
Luminous Cottage
A quiet five-stop sumi arc with a confident middle — #7e0336 carries the weight and #ef8da2 carries the air, with #aa3e5c, #c95a76 and #d17187 bridging in tetradic formation. Built for hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA as a text pair.
