Wow, I appreciate all the responses that suddenly came in today!
The take away that I'm getting is that colour is entirely subjective and there is no such thing as "real." I don't really disagree, but when I accidentally read the article by Clark it made me stop and think and I spent a few days mulling all what he said. And, why not?
I don't agree with some of the comments that the photos he posted (processed to tame the reds) are "boring." They are different than the usual fare, and the reds show an interesting distribution of colours usually rendered as all red. Anyway, it's probably not worth beating this dead horse anymore!
Maybe anyone who comments on any posted photos in the deep sky section should refrain from making any comments about colour. To the contrary, quite a few posts pick on colour if it doesn't happen to fit ones own notion of what looks "real!" And, it's pretty hard to deny that Australia's most famous astro imaging competition puts quite an emphasis on colour that is supposedly "real and natural." So, while there may be agreement on one hand that colour is fake, it's also pretty clear that somewhere deep in the collective psyche their exists a notion that colour needs to look a certain way or it isn't right. We just don't all agree one what that means.
