Retro palette
Dusky Oasis
Five retro stops with room to breathe — #7a2b00 grounds, #b14c1d and #d0683b do the talking, #d77e59 softens, #f69a74 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.
