After watching poita's link for the DaVinci color adjustments demo, for it's professional nomenclature, I see that the "Y" in YRGB is merely luminance ... the linked +/- movement of individual R-G-B separations as a whole or on spectrum areas. That function is in the paint program I'm using and in the Gradation Curves plug-in for VirtualDub (both simply identified as "RGB"). Nothing proprietary about it.

In fact, there is no such thing as YRGB per se. It all starts as RGB --> is manipulated by luminance and/or saturation and/or tint and/or the individual R-G-Bs and/or any other function --> ends as RGB (now modified). So, there is no translation for it, nor is one needed.

Thanks for the ACES links -- I approve of generalized future-proofing. :)
