I must not have made myself clear about what I was arguing. I was _not_
attempting to argue that YUV is substandard or better than RGB. I _was_
talking about the digital RGB format and the necessity for so many colors.
I have little or no understanding of the YUV format. I was only saying that,
for an RGB display, the fact that N colors won't fit has nothing to do with why
that many colors are available. I have heard the "won't fit" premis many
times, as it relates to digital RGB graphics cards, and it continually strikes
me as a paramount of illogic.
In fact, I would hypothesize that my point is true regardless of the format
(RGB, YUV, CMYK, HLS) so long as it is digitally encoded. To speak
inductively, I would say that a digital encoding system must have enough
references within each component of the digital code to eliminate distinct
separations between areas of pixels a with single differing component.
Further, the fact that the total combination of necessary references per
component exceeds the number of pixels (ie total # of addressable colors "won't
fit") in the display device at once is irrelevant.
For analog, however, the point is nullified since the distance between
references in any given component become infinately small, and the whole idea
of references is invalid.
Anyway, the last thing I want to do is get into an arguement with you. <BG> I
just wanted to point out what I feel is a popular misconception.
