Harvest Brook
Five stops tuned to sit together without fighting — #9b0755 ink anchors the set, #ffa5c4 opens it up, and #c8477d, #e86498, #ef7ea7 cross the middle in a complementary arrangement. Harvest Brook suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
