Blue Hour palette
Spruce Delta
A quiet five-stop blue hour arc with a confident middle — #1668a2 carries the weight and #b0d9ff carries the air, with #4c92cc, #68aeea and #83bef1 bridging in tetradic formation. Built for dashboards where status colors must survive color-vision differences. The darkest and lightest stops clear AA for large text.
