Blue Hour palette
Opal Archive
Five stops tuned to sit together without fighting — #004175 ink anchors the set, #6bb0f6 opens it up, and #0068b5, #2d84d3, #4f93d7 cross the middle in a tetradic arrangement. Opal Archive suits dashboards where status colors must survive color-vision differences. The darkest and lightest stops clear AA as a text pair.
