Yuzu Grove
Five stops tuned to sit together without fighting — #a83200 ink anchors the set, #ffc0ad opens it up, and #d95e37, #f97b54, #ff9371 cross the middle in a tetradic arrangement. Yuzu Grove suits book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
