Inked Clearing
Five sumi stops with room to breathe — #7c0029 grounds, #aa3a4e and #c95667 do the talking, #d06e7a softens, #ef8995 lifts. The split-complementary bones keep it coherent across event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
