Nebula palette
Nightfall Lagoon
Five nebula stops with room to breathe — #006589 grounds, #2890bc and #4aacd9 do the talking, #6cbbe2 softens, #8bd8ff 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.
