Disco palette
Birch Mill
Five stops tuned to sit together without fighting — #005576 ink anchors the set, #77c7f2 opens it up, and #0080af, #349ccc, #5aaad4 cross the middle in a tetradic arrangement. Birch Mill suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
