Seafoam Canyon
Five stops tuned to sit together without fighting — #8d0345 ink anchors the set, #ff94b3 opens it up, and #ba426c, #d95e86, #e17797 cross the middle in a split-complementary arrangement. Seafoam Canyon suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
