Monochrome palette
Muslin Kiln
Five monochrome stops with room to breathe — #006e08 grounds, #399a38 and #57b755 do the talking, #75c371 softens, #91e18d lifts. The complementary bones keep it coherent across book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
