Sumi palette
Porcelain Foundry
Five sumi stops with room to breathe — #7c2a3a grounds, #a75561 and #c5707b do the talking, #ce848d softens, #eca0a8 lifts. The split-complementary bones keep it coherent across bike-shop liveries that survive mud and sun. The darkest and lightest stops clear AA as a text pair.
