Whispering Prairie
Five stops tuned to sit together without fighting — #7f0f00 ink anchors the set, #f88c78 opens it up, and #b33b28, #d25843, #d9705d cross the middle in a complementary arrangement. Whispering Prairie suits bike-shop liveries that survive mud and sun. The darkest and lightest stops clear AA as a text pair.
