Nebula palette
Tranquil Dairy
Five nebula stops with room to breathe — #00506d grounds, #007aa5 and #3396c2 do the talking, #57a4ca softens, #74c0e8 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.
