Pastel palette
Harbor Fen
Five pastel stops with room to breathe — #005052 grounds, #007c7e and #339799 do the talking, #57a5a6 softens, #73c1c2 lifts. The tetradic bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
