Butter Bluff
Five stops tuned to sit together without fighting — #00545a ink anchors the set, #76c6cd opens it up, and #008089, #349ca5, #59a9b0 cross the middle in a analogous arrangement. Butter Bluff suits museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA for large text.
