Excellent!
So nice to see a globular cluster in plausible colours. Even the professional popular sites are not above making them blue-white so they look pretty, but they cannot possibly be ten billion years old and blue, or even blue-white. They can't even be ten million years old and blue. As you say, they will have a smattering of blue stars due to the collision and merger of close binaries, and they will be bright and salient, but they are in the extreme minority. You have it right.
Best,
Mike
