A few weeks ago, a vertical line about 5 cm wide appeared in the middle of my Macbook's display. The colors inside the line are distorted in a regular pattern: whites are always pinkish-purple, blues are a bit greenish, greens are only a bit lighter, greys do not change at all. This is why I am using dark theme on MacOS and all websites.

I've consulted repair services and they are convinced it's the LCD matrix issue and there is no way to replace the matrix without replacing the entire display itself, which costs about 700 USD. At the moment, I cannot afford the repair.

I was wondering if there is software that can provide a temporary solution to color distortion. Maybe it can adjust the pixel colors inside the line so that they correspond to the actual rgb value they are supposed to be.

I realize it sounds kinda dumb and may not be possible at all but still.
