Aurora palette
Sugar Moor
Five aurora stops with room to breathe — #004558 grounds, #006f8b and #308aa7 do the talking, #5298b1 softens, #6eb4cd lifts. The split-complementary 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.
