Aurora palette
Rumpled Cove
Five aurora stops with room to breathe — #004a28 grounds, #157646 and #39915f do the talking, #579e73 softens, #73ba8e lifts. The tetradic 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.
