Emerald Outpost
Five stops tuned to sit together without fighting — #004c53 ink anchors the set, #71bcc5 opens it up, and #007782, #32929d, #55a0a9 cross the middle in a analogous arrangement. Emerald Outpost suits museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA for large text.
