Aurora palette
Mossy Gallery
Five aurora stops with room to breathe — #394f97 grounds, #6079c1 and #7a95df do the talking, #8da5e5 softens, #abc2ff 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.
