Blue Hour palette
Amber Library
Five blue hour stops with room to breathe — #00647a grounds, #0090af and #38accc do the talking, #61bad5 softens, #7fd7f3 lifts. The split-complementary bones keep it coherent across museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA for large text.
