Monochrome palette
Lupine Atelier
Five monochrome stops with room to breathe — #004c18 grounds, #30753d and #4c9057 do the talking, #649d6c softens, #7fb986 lifts. The monochromatic bones keep it coherent across book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
