Willow Manor
Five stops tuned to sit together without fighting — #a02100 ink anchors the set, #ffb19e opens it up, and #d24f33, #f26c4f, #f8856c cross the middle in a split-complementary arrangement. Willow Manor suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
