Vernal Garret
Five stops tuned to sit together without fighting — #8f3446 ink anchors the set, #ffadb7 opens it up, and #bb606e, #d97b89, #e2909b cross the middle in a tetradic arrangement. Vernal Garret suits bike-shop liveries that survive mud and sun. The darkest and lightest stops clear AA for large text.
