Gleaming Plaza
Five stops tuned to sit together without fighting — #7f2100 ink anchors the set, #ff9172 opens it up, and #ba3f17, #d95c37, #e07556 cross the middle in a complementary arrangement. Gleaming Plaza suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
