Vintage Abbey
Five stops tuned to sit together without fighting — #005488 ink anchors the set, #85c5fb opens it up, and #2f7db9, #4d99d7, #69a8dd cross the middle in a analogous arrangement. Vintage Abbey suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
