Bitter Fen
Five stops tuned to sit together without fighting — #781000 ink anchors the set, #ef8a77 opens it up, and #aa3b28, #c95743, #d06f5c cross the middle in a tetradic arrangement. Bitter Fen suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
