Retro palette
Olive Kiln
Five retro stops with room to breathe — #74121b grounds, #9f4242 and #bd5d5b do the talking, #c5726f softens, #e48e8a lifts. The tetradic bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
