The CW color problems

For the past several weeks the color has been very off on the CW channel. All of the people are blue and everything else is yellow. Even the commercials look like this. I’ve searched everywhere, but cannot find where anyone else is having a similar issue. How do I fix it? Do I need to contact someone? One time the color randomly switched back to looking normal half way through my show, but then switch back at some point and has been stuck blue and yellow ever since.
