Sumi palette
Copper Foundry
A quiet five-stop sumi arc with a confident middle — #87361b carries the weight and #f7ac94 carries the air, with #b26147, #d07c61 and #d99079 bridging in tetradic formation. Built for newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA for large text.
