Pepper Atelier
Five stops tuned to sit together without fighting — #006599 ink anchors the set, #a1d6ff opens it up, and #428fc4, #5fabe2, #7bbae9 cross the middle in a analogous arrangement. Pepper Atelier suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
