Retro palette
Pewter Library
Five retro stops with room to breathe — #7c1200 grounds, #b13a25 and #d05740 do the talking, #d76f5b softens, #f68b76 lifts. The split-complementary bones keep it coherent across book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
