No, during TOS, Jerry Finnerman was setting his key lights on Uhura. When the key spot isn't aimed properly, in lighting jargon they're 'black'. So Finnerman's hollering up to one of the guys on the light rig, saying "No, no, she's black! She's black!"
Then he realizes Nichelle is sitting right there and tries to apologize. She cuts him off with "...but comely." Then later, Nimoy and others could break her up by coming up beside her and saying softly "but comely."
I think Steven Whitfield tells the story in The Making of Star Trek.
