Crimson Alley
Five stops tuned to sit together without fighting — #004673 ink anchors the set, #6eb5f2 opens it up, and #006eb1, #2f8acf, #5299d4 cross the middle in a triadic arrangement. Crimson Alley suits bike-shop liveries that survive mud and sun. The darkest and lightest stops clear AA for large text.
