Blue Hour palette
Polar Delta
Five blue hour stops with room to breathe — #890c00 grounds, #ba402f and #d95d4a do the talking, #e07564 softens, #ff927f lifts. The triadic bones keep it coherent across museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA as a text pair.
