Monochrome palette
Elder Lane
Five monochrome stops with room to breathe — #00658b grounds, #0091c5 and #39ade3 do the talking, #62bcea softens, #8fd8ff 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.
