Woodsmoke Atelier
Five stops tuned to sit together without fighting — #9b2000 ink anchors the set, #ffac99 opens it up, and #d64322, #f66241, #fc7d61 cross the middle in a triadic arrangement. Woodsmoke Atelier suits bike-shop liveries that survive mud and sun. The darkest and lightest stops clear AA for large text.
