Acid palette
Opal Clearing
Five acid stops with room to breathe — #5c3800 grounds, #905a00 and #ac752b do the talking, #b6864d softens, #d4a268 lifts. The monochromatic bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
