Monochrome palette
Kiln Dairy
Five monochrome stops with room to breathe — #00416b grounds, #0069a7 and #2e84c4 do the talking, #5093ca softens, #6bb0e8 lifts. The analogous bones keep it coherent across book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
