Nebula palette
Polar Atelier
Five stops tuned to sit together without fighting — #004477 ink anchors the set, #6db4f8 opens it up, and #006cb7, #2f88d5, #5197da cross the middle in a monochromatic arrangement. Polar Atelier suits packaging that photographs well under harsh retail light. The darkest and lightest stops clear AA as a text pair.
