Copper Harbor
Five stops tuned to sit together without fighting — #9c0e61 ink anchors the set, #ffa9cd opens it up, and #c94a89, #e867a4, #f080b3 cross the middle in a tetradic arrangement. Copper Harbor suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
