Earthen Bluff
Five stops tuned to sit together without fighting — #1d5b93 ink anchors the set, #9ccdff opens it up, and #4c85bd, #67a1db, #7fb0e2 cross the middle in a analogous arrangement. Earthen Bluff suits museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA for large text.
