Sumi palette
Crimson Manor
A quiet five-stop sumi arc with a confident middle — #910020 carries the weight and #ff9797 carries the air, with #c04048, #e05d62 and #e67677 bridging in tetradic formation. Built for flower-shop wraps and delivery van livery together. The darkest and lightest stops clear AA as a text pair.
