What is the Make/Model of the computer giving you this problem? Is it a Desktop PC or a laptop/notebook?
Did this computer come with W10 or did you upgrade it from an earlier version of Windows (WIN7/8/8.1/8.1.1 or earlier)? If so, which version?
I would suggest borrowing a standard LCD flat screen computer monitor from a friend and plugging that in. If that resolves the problem and it abates, you probably have a problem with your computer's video driver (GPU) syncing with your TV in W10. That might mean you just need to find the make/model of your GPU card or embedded chip and go to that website, such as NVIDIA, and download the latest driver for that card or chip to your W10 setup. That will often fix the problem.
However, if you do the external LCD monitor test, and the problem follows over to the external monitor, you probably have a faulty driver for your GPU card or chip; simply visit the manufacturer's website and download and udpate your video driver. This should fix it. If it does not, that could indicate a failure of your GPU card or embedded chip and it must be replaced. In most instances this requires a new discrete card if it's a desktop PC; if a laptop or notebook you can't replace the GPU chip as it's hardwired in the Motherboard in 99% of the cases so then it must be a Motherboard replacement; $175-$400 and up just for the part, can be up to $1100 more for labor depending on your location if overseas.
Try these simple tests. Remember you can buy used LCD monitors in yard sales for under $30, or even in Thrift stores. Personally, I'd buy a new LCD, you can get them online such as from Tiger Direct for under $100.
You can also take your TV to a friend or neighbors computer who has W10 running ok with no video coloring issues, and plug in your TV to his computer--if the problem appears on his computer--that TV monitor has failed has caused your problem all along and must be replaced.
