Aurora palette
Cornsilk Moor
Five aurora stops with room to breathe — #00515b grounds, #007c8b and #3397a7 do the talking, #57a5b2 softens, #74c1cf 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 for large text.
