Odo's beige uniform
In 2369, referring to his Bajoran Militia uniform color, Lwaxana Troi described Odo's role on Deep Space 9 as being "the thin beige line between order and chaos." The Changeling affirmed this, saying it was his job. (DS9: "The Forsaken")
In 2372, Kathryn Janeway and Chakotay had a choice between having the gray side of the modular shelters they were constructing facing inside, or the beige. Chakotay suggested the beige face the inside, to which Janeway agreed, saying she'd always looked better in that color. (VOY: "Resolutions")
