Sumi palette
Opal Cellar
A quiet five-stop sumi arc with a confident middle — #983e00 carries the weight and #ffbc9d carries the air, with #d75b00, #f77832 and #fd905b 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.
