Gloaming Shrine
Five stops tuned to sit together without fighting — #004272 ink anchors the set, #7bb0e4 opens it up, and #2a6aa2, #4685bf, #6094c6 cross the middle in a monochromatic arrangement. Gloaming Shrine suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
