Retro palette
River Alley
Five retro stops with room to breathe — #062faa grounds, #2f5fd4 and #487cf3 do the talking, #608ef4 softens, #86adff 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.
