Sumi palette
Silken Cellar
A quiet five-stop sumi arc with a confident middle — #a33500 carries the weight and #ffbea8 carries the air, with #d55f34, #f57b51 and #fb936f 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.
