Correct colour of stars in globs has been a topic recently on this site. Globs are older stars and typically dominated with sunlike yellow old stars. I wonder if it should show more yellow stars or is the colour correct (not a criticism more of a question).

I agree with Greg, it should be yellower. Gratton (2003) calculated it as been 13.4 billion years old, a paper in 1996 had it at 13.5-14.6 and Wikipedia says 11.5.
A study from Swinburne in 2010 using HST data:

11.78 billion years old. Off the top of my head should have the average star mass at 0.9 solar masses.
Very nicely resolved however!
