Aurora palette
Birch Square
Five stops tuned to sit together without fighting — #293ea0 ink anchors the set, #9bb5ff opens it up, and #4e6aca, #6786e8, #7b97ec cross the middle in a complementary arrangement. Birch Square suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
