Monochrome palette
Tawny Gallery
Five stops tuned to sit together without fighting — #2d4f00 ink anchors the set, #92c16b opens it up, and #497b00, #63972d, #77a450 cross the middle in a split-complementary arrangement. Tawny Gallery suits book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
