Thistled Brook
Five stops tuned to sit together without fighting — #9d2e21 ink anchors the set, #ffb5a8 opens it up, and #ca5d4d, #e97967, #f08f7f cross the middle in a split-complementary arrangement. Thistled Brook suits packaging that photographs well under harsh retail light. The darkest and lightest stops clear AA for large text.
