Monochrome palette
Pepper Bookshop
Five stops tuned to sit together without fighting — #3e5b00 ink anchors the set, #a9cd7c opens it up, and #618622, #7ba241, #8eb060 cross the middle in a split-complementary arrangement. Pepper Bookshop suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
