Brisk Brook
Five stops tuned to sit together without fighting — #006564 ink anchors the set, #7fdad7 opens it up, and #009391, #39afad, #61bcba cross the middle in a split-complementary arrangement. Brisk Brook suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
