Aurora palette
Larkspur Courtyard
Five aurora stops with room to breathe — #004a52 grounds, #007581 and #31909c do the talking, #549ea8 softens, #70bac4 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.
