Oaken Fen
Five stops tuned to sit together without fighting — #223b88 ink anchors the set, #90adf2 opens it up, and #4865b1, #6180cf, #7591d4 cross the middle in a tetradic arrangement. Oaken Fen suits music artwork with loud darks and a glowing accent. The darkest and lightest stops clear AA as a text pair.
