Cobalt Beacon
Five stops tuned to sit together without fighting — #004b70 ink anchors the set, #71bbec opens it up, and #0074aa, #318fc7, #559ece cross the middle in a monochromatic arrangement. Cobalt Beacon suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
