Blue Hour palette
Gleaming Reef
Five stops tuned to sit together without fighting — #004870 ink anchors the set, #70b8ee opens it up, and #0071ac, #308cc9, #539bd0 cross the middle in a split-complementary arrangement. Gleaming Reef suits dashboards where status colors must survive color-vision differences. The darkest and lightest stops clear AA as a text pair.
