Nebula palette
Silvery Bluff
Five nebula stops with room to breathe — #7d0500 grounds, #ad3a2c and #cc5646 do the talking, #d36e5f softens, #f28a7a lifts. The 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.
