Aurora palette
Copper Brook
Five aurora stops with room to breathe — #2f4dc8 grounds, #557bf3 and #779bff do the talking, #8eadff softens, #b7ccff lifts. The split-complementary bones keep it coherent across book covers that read at thumbnail size. The darkest and lightest stops clear AA for large text.
