Sumi palette
Umber Reef
A quiet five-stop sumi arc with a confident middle — #990035 carries the weight and #ffa1ab carries the air, with #ca405b, #ea5e75 and #f07889 bridging in tetradic formation. Built for newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA as a text pair.
