Hi Eric,

I hope you're not working under the mistaken assumption that human color vision is a constant and invariable. I can assure you that it varies a great deal and I'm not talking about color blindness or other pathological conditions - I talking about normal human variability in color perception.

There is a "Standard Model" that is the technical baseline.  It represents what most people can see.

Even were human vision a constant, which it is decidedly not, why would a "weakness" (the RGB model as developed in CFA technology) be the optimal solution for producing the best color replication from sensor capture?

The RGB model predates CFA technology by 50 years.   Are you playing intentionally ignorant here of color science?

Best regards,

As I said before - the problem is in the RGB Color model not in the sensors which are capable of delivering more information in an image file.

That's circular reasoning - obviously the sensor has a internally consistent color model. But the best color model that describes human vision is RGB - that's been established for over 80 years now. That's the accuracy that is of interest to anyone doing photographic work to be viewed by humans.
