Aurora palette
Frosty Heath
Five aurora stops with room to breathe — #1f4e88 grounds, #4a77b1 and #6492ce do the talking, #7aa2d6 softens, #96bef4 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 for large text.
