Ebony Canyon
Five stops tuned to sit together without fighting — #0067a7 ink anchors the set, #b0d9ff opens it up, and #4492d2, #61aef0, #7ebef6 cross the middle in a tetradic arrangement. Ebony Canyon suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
