Opal Beacon
Five stops tuned to sit together without fighting — #3165a2 ink anchors the set, #b8d7ff opens it up, and #5d8fcc, #78abea, #8fbbf1 cross the middle in a split-complementary arrangement. Opal Beacon suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
