Rustic Manor
Five stops tuned to sit together without fighting — #a52804 ink anchors the set, #ffb8a7 opens it up, and #d25a3e, #f27659, #f88e75 cross the middle in a complementary arrangement. Rustic Manor suits bike-shop liveries that survive mud and sun. The darkest and lightest stops clear AA for large text.
