Wheat Mill
Five stops tuned to sit together without fighting — #7d2700 ink anchors the set, #f29b7d opens it up, and #ad4f2d, #cb6a48, #d37f62 cross the middle in a triadic arrangement. Wheat Mill suits book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
