Grassy Reef
Five stops tuned to sit together without fighting — #a1391d ink anchors the set, #ffc0af opens it up, and #ce674c, #ed8367, #f59980 cross the middle in a split-complementary arrangement. Grassy Reef suits packaging that photographs well under harsh retail light. The darkest and lightest stops clear AA for large text.
