Specific Can you please fix the colours/white balance on this photo

The colours looks weird on this photo.
Could you please fix it? The women wear white dresses

basically, there are three colors on this picture, I assume because of the strong color lights on the theater, the picture only contains only reds, magentas and a little bit of blue on the boy shirt .
if you want the dress white and you remove the redds and magentas the picture it's just black and white, if you only remove the reds on the dress it would look really weird and fake.

So the only solution I see, it's making it Black and white and paint the entire picture....

perfect.
I was very silly for not shooting in raw. (I can fix the colours on those with canon's free Digital Photo Professional But it does not work with jpg.
