Strange pink spots and unwanted pink-ish light parts

I am making an Oculus Quest app. It is kind of a laminated floor and wall paper demo room, with realistic items, and details. My problem is that, in some case there are some strange pink spots, mainly on the wall, and parts of the floor seems too pinkish. In the original texture does not have the pinkish color on it. This is not there on every floor - even when two samples are almost look the same - and every wallpaper, but on which it is there, it is constantly there in any circumstances. The textures was made by me, with the same camera, and the same photoshop effects.
