Aurora palette
Herbal Marsh
Five aurora stops with room to breathe — #005e64 grounds, #008b93 and #37a7af do the talking, #5eb4bb softens, #7bd1d8 lifts. The triadic 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.
