Aurora palette
Marble Dock
Five aurora stops with room to breathe — #1e3ca6 grounds, #4469d0 and #5d85ef do the talking, #7297f1 softens, #96b5ff lifts. The analogous bones keep it coherent across event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
