Sumi palette
Vintage Square
Five stops tuned to sit together without fighting — #7a2e00 ink anchors the set, #f29e7a opens it up, and #ad5226, #cb6d42, #d3825e cross the middle in a monochromatic arrangement. Vintage Square suits bike-shop liveries that survive mud and sun. The darkest and lightest stops clear AA for large text.
