Monochrome palette
Luminous Atelier
Five monochrome stops with room to breathe — #005a82 grounds, #3783af and #549fcc do the talking, #70add4 softens, #8ccaf2 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.
