I don't have the book in front of me, but I think the Solow/Justman book mentions an incident of color correction regarding Spock which mirrored the green makeup issue.
There was a story about them putting Brent Spiner in a rainbow of face colours to see how they'd photograph, and also how each colour would appear on b/w TV. But I don't recall Nimoy photos getting colour corrected by the lab; that was Majel in green (and they also tried some Spock-like makeup on her as Number One).
The kicker to the Data story is that after doing all these multiple color tests for Data, they bring in Roddenberry, so he can make the final choice. The first one to come up is the whitish-gold we all know and love, GR says, "That one," and leaves the screening room without even bothering with the umpteen other tests they did.
