Blue Hour palette
Emerald Depot
Five stops tuned to sit together without fighting — #15488b ink anchors the set, #8db9f7 opens it up, and #4171b5, #5b8cd3, #729cd9 cross the middle in a monochromatic arrangement. Emerald Depot suits packaging that photographs well under harsh retail light. The darkest and lightest stops clear AA for large text.
