Blue Hour palette
Steely Reef
Five stops tuned to sit together without fighting — #00507c ink anchors the set, #74c1fa opens it up, and #0379b8, #3395d6, #58a4dc cross the middle in a split-complementary arrangement. Steely Reef suits packaging that photographs well under harsh retail light. The darkest and lightest stops clear AA for large text.
