Aurora palette
Stormy Saloon
Five aurora stops with room to breathe — #3f54a9 grounds, #667fd4 and #809bf2 do the talking, #94acf7 softens, #b9cbff lifts. The split-complementary 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.
