Aurora palette
Butter Foundry
Five aurora stops with room to breathe — #1a784b grounds, #51a274 and #6ebf8f do the talking, #88cca3 softens, #a5e9bf 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.
