Vintage Atelier
Five monochrome stops with room to breathe — #006437 grounds, #2d905a and #4dac74 do the talking, #6cb989 softens, #88d6a4 lifts. The triadic bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
