Monochrome palette
Sugar Moor
Five stops tuned to sit together without fighting — #006471 ink anchors the set, #7fd8e8 opens it up, and #0091a3, #38adbf, #61bbca cross the middle in a split-complementary arrangement. Sugar Moor suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
