There's a lot to consider there. I tried to normalize the white balance in FitStacker using the star's BV index as a reference, but it's tricky with this one. If you just look at it visually, I've seen processed versions of photos of M 13 with the blue region, the yellow region, and they all look noticeably different. Personally, I felt this version here looked best this way.
