I am new to photography, so I ran into a problem when trying to edit a photo in Rawtherapee where my picture looks like it has red and green blotches all over it. I took this photo with ProShot on my Pixel 6.

Is there anyway to fix this?

    Most likely some processing that boosted a color channel more than the others when trying to make things lighter, but hard to tell without seeing your initial picture.

So when you increase their luminosity you increase mostly the red part and their tone shifts towards a more visible red.
