Aurora palette
Lichen Bakery
Five aurora stops with room to breathe — #00494e grounds, #00747b and #318f96 do the talking, #539ca2 softens, #6fb9be lifts. The 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.
