Linen Abbey
Five sumi stops with room to breathe — #7a2831 grounds, #a55358 and #c36e72 do the talking, #cc8284 softens, #ea9da0 lifts. The split-complementary 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.
