I just recovered some deleted photos, and noticed they are all pink. Is there any way for me to fix all my photos?
That's not pink — that's magenta. The difference is significant because magenta is the mix of blue and red primaries, with no green. That implies that the green channel information for that part of the file is damaged. But also, it's pretty clear that most of the image is messed up far beyond beyond that. I'd write this one off as not salvageable.
If you still have the memory card, you might try different recovery software. If that doesn't work, I suppose your best bet is to take another photo.
