Monochrome palette
Zephyr Alley
Five monochrome stops with room to breathe — #004a5b grounds, #00758d and #3190a9 do the talking, #549eb3 softens, #71bad0 lifts. The complementary bones keep it coherent across book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
