Lichen Lighthouse
Five stops tuned to sit together without fighting — #9c4048 ink anchors the set, #ffc1c2 opens it up, and #c86c71, #e7878c, #ef9d9f cross the middle in a tetradic arrangement. Lichen Lighthouse suits bike-shop liveries that survive mud and sun. The darkest and lightest stops clear AA for large text.
