Retro palette
Mustard Chapel
Five retro stops with room to breathe — #8a0037 grounds, #c1305a and #e14f74 do the talking, #e76c86 softens, #ff8fa4 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.
