>>117322467Same thing that happened to Susan Oliver when painted up as an Orion slave girl during filming of "The Menagerie." The photo tech developing the dailies of the pilot saw her and said, "My God, that woman is green," and tinted her skin tone back to pasty pale pink. (Imagine Roddenberry and company's reaction to this when reviewing the dailies the next day.)
In Tendi's case, perhaps just a little roleplay in the holodeck as to what she'd look like as a human.
