What is your source for this information ...?
It is well-known that the unmasking scene was shot in Technicolor and in Black and White. I believe one of the DVD or Blu-ray commentaries as well as Phillip Riley's book (admittedly not the most reliable of sources) has that information. The Technicolor scene was not supposed to be used because the hot studio lights would cause the seam where Chaney's bald cap met his forehead to show. We have two versions of the unmasking scene, one of which may have been originally shot in Technicolor or at the same time as the Technicolor from a 2nd camera angle.
