A strong magenta cast in a recovered RAW file usually points to corruption, especially loss or damage in the green channel data. If most of the image also looks scrambled or otherwise wrong, it’s generally not something you can fully repair in editing.

Your best option is to try recovering the card again with different recovery software, if you still have the original memory card and haven’t written anything new to it. Sometimes one tool can recover files more completely than another.

If repeated recovery attempts produce the same result, the files are likely not salvageable. In that case, there may be no practical fix beyond retaking the photos if possible.
