Retro palette
Copper Bluff
Five retro stops with room to breathe — #6d005f grounds, #a02b8d and #be49a9 do the talking, #c764b3 softens, #e580d0 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.
