Umber Archive
Five stops tuned to sit together without fighting — #005056 ink anchors the set, #74c1c8 opens it up, and #007c84, #33979f, #57a5ab cross the middle in a tetradic arrangement. Umber Archive suits museum exhibition graphics with long sightlines. The darkest and lightest stops clear AA for large text.
