Twilit Marsh
Five stops tuned to sit together without fighting — #007471 ink anchors the set, #86e9e6 opens it up, and #00a29f, #3cbfbb, #68ccc8 cross the middle in a analogous arrangement. Twilit Marsh suits music artwork with loud darks and a glowing accent. The darkest and lightest stops clear AA for large text.
