Blue Hour palette
Marble Granary
A quiet five-stop blue hour arc with a confident middle — #00516b carries the weight and #75c2e4 carries the air, with #007ca1, #3398be and #58a6c6 bridging in tetradic formation. Built for museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA for large text.
