Quiet Reef
Five stops tuned to sit together without fighting — #7b1e3d ink anchors the set, #ec97aa opens it up, and #a74b64, #c5667e, #ce7b8f cross the middle in a tetradic arrangement. Quiet Reef suits bike-shop liveries that survive mud and sun. The darkest and lightest stops clear AA as a text pair.
