Problem with my Laptop Screen

Hello everyone i seem to have a problem with my laptop screen, all the areas that are meant to be white are a teal color. For example the white within the search bar is a teal. It started last night randomly while i was watching a youtube video.

I found an image online that looks similar to what mine does
