Lunar Brook
Five stops tuned to sit together without fighting — #007273 ink anchors the set, #85e7e8 opens it up, and #00a0a2, #3cbdbe, #67cacb cross the middle in a tetradic arrangement. Lunar Brook suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
