Blue Hour palette
Porcelain Fen
Five blue hour stops with room to breathe — #115fa9 grounds, #478ad3 and #63a6f1 do the talking, #7db6f7 softens, #acd3ff 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.
