Nebula palette
Sloe Heath
Five nebula stops with room to breathe — #7d1300 grounds, #bc2c10 and #dc4c32 do the talking, #e26951 softens, #ff876f 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 as a text pair.
