Sumi palette
Coral Bluff
A quiet five-stop sumi arc with a confident middle — #8a0002 carries the weight and #ff9081 carries the air, with #c23127, #e25143 and #e86d5e bridging in triadic formation. Built for book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
