Opal Ridge
Five stops tuned to sit together without fighting — #711d00 ink anchors the set, #e98f75 opens it up, and #a44225, #c25d40, #ca735a cross the middle in a monochromatic arrangement. Opal Ridge suits bike-shop liveries that survive mud and sun. The darkest and lightest stops clear AA as a text pair.
