The facilitator is dead wrong, raw is raw, it has no actual color space at this stage of life
This statement brings up a previous
discussion on this site, where such luminaries in the digital imaging world as Thomas Knoll opined that the raw file does indeed have a color space. Chapter 6 of the
DNG specification is devoted wholly to the subject of mapping the
camera color space to the CIE XYZ space.
To paraphrase Bill Clinton, "It depends on what the meaning of the word 'is' is. If the--if he--if 'is' means is and never has been, that is not--that is one thing. If it means there is none, that was a completely true statement....". In other words, it depends on definition and how that definition is parsed.
Since that thread was argued, Douglas Kerr has published a very illuminating 27 page PDF,
Digital camera sensor colorimetry. The discussion involves the Luther-Ives criteria, matrix transformations, imaginary primaries, metameric matches, and negative RGB values. Very interesting reading for the technically minded.
The conclusion that the camera does not have a strictly defined color space, but in practice it is often convenient to imagine that it does. Both sides of this argument can claim victory
