Halcyon Fjord
Five stops tuned to sit together without fighting — #006e6c ink anchors the set, #83e3e0 opens it up, and #009c9a, #3bb8b6, #65c6c3 cross the middle in a triadic arrangement. Halcyon Fjord suits museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA for large text.
