Industrial palette
Pearl Canyon
Five industrial stops with room to breathe — #8b0029 grounds, #bb3d4f and #da5a69 do the talking, #e1737d softens, #ff9199 lifts. The tetradic bones keep it coherent across book covers that read at thumbnail size. The darkest and lightest stops clear AA as a text pair.
