Retro palette
Marble Granary
Five retro stops with room to breathe — #4e3a00 grounds, #7d5e00 and #98782a do the talking, #a4884b softens, #c0a466 lifts. The triadic bones keep it coherent across museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA as a text pair.
