As to the correct colour Greg, NGC 6752 sits in a area of sky with very little obscuration/extinction from dust, so, unlike many other globs, there is almost no interstellar reddening. If you look closely, there is indeed a nice spread of mostly yellow-white stars, with a good spattering of yellow-orange ones plus a few tiny almost red ones and then quite a few blue stragglers,. These colours and hues will vary somewhat across different screens but overall this is certainly what we would expect but, as you say, perhaps the bulk of the yellow-white stars could be a little more yellow/red..?

Yes I saw that spread of colours, that's why its more of a question than a comment about the image. For sure Omega is often shown as too blue/white. I am not sure how that translates to other globs.
