Aurora palette
Granite Pavilion
Five stops tuned to sit together without fighting — #403f80 ink anchors the set, #acb0ec opens it up, and #6668a9, #8083c6, #9094ce cross the middle in a split-complementary arrangement. Granite Pavilion suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
