Blue Hour palette
Indigo Delta
Five stops tuned to sit together without fighting — #00476f ink anchors the set, #6fb7ed opens it up, and #0070ab, #308bc8, #539acf cross the middle in a tetradic arrangement. Indigo Delta suits craft brewery cans lined up in a cooler door. The darkest and lightest stops clear AA as a text pair.
