Crimson Lighthouse
Five sumi stops with room to breathe — #7d2804 grounds, #a85437 and #c66f51 do the talking, #ce8369 softens, #ed9f85 lifts. The analogous bones keep it coherent across newsletters where the header, links, and footers share one voice. The darkest and lightest stops clear AA as a text pair.
