Blue Hour palette
Emerald Harbor
A quiet five-stop blue hour arc with a confident middle — #00578c carries the weight and #8ac9fe carries the air, with #3581bb, #529dd9 and #6eacdf bridging in tetradic formation. Built for museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA for large text.
