Blue Hour palette
Amber Square
Five stops tuned to sit together without fighting — #004873 ink anchors the set, #70b8f2 opens it up, and #0071b0, #308dcd, #539cd3 cross the middle in a tetradic arrangement. Amber Square suits craft brewery cans lined up in a cooler door. The darkest and lightest stops clear AA as a text pair.
