Greige Pavilion
Five stops tuned to sit together without fighting — #9a381d ink anchors the set, #ffb9a6 opens it up, and #c6654b, #e58166, #ed967e cross the middle in a split-complementary arrangement. Greige Pavilion suits packaging that photographs well under harsh retail light. The darkest and lightest stops clear AA for large text.
