Sumac Crossing
Five stops tuned to sit together without fighting — #0061a8 ink anchors the set, #abd4ff opens it up, and #008bec, #4ca8ff, #72b8ff cross the middle in a analogous arrangement. Sumac Crossing suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
