Blue Hour palette
Seafoam Reef
Five blue hour stops with room to breathe — #004b8e grounds, #2974c3 and #4690e1 do the talking, #63a0e6 softens, #84bdff lifts. The tetradic bones keep it coherent across museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA for large text.
