Nebula palette
Umber Mill
Five stops tuned to sit together without fighting — #004467 ink anchors the set, #71b3e0 opens it up, and #126d9e, #3688bb, #5697c2 cross the middle in a analogous arrangement. Umber Mill suits packaging that photographs well under harsh retail light. The darkest and lightest stops clear AA as a text pair.
