Foxglove Mill
Five stops tuned to sit together without fighting — #b02000 ink anchors the set, #ffbfb1 opens it up, and #e1543a, #ff7459, #ff917b cross the middle in a split-complementary arrangement. Foxglove Mill suits bike-shop liveries that survive mud and sun. The darkest and lightest stops clear AA for large text.
