Hello,
Try following these steps to resolve your issue:
- Press
Windows + Ctrl + C. This is a shortcut that toggles color filters on and off. If it works, your colors should come back. - Go to Settings → Ease of Access → Color Filters. Make sure Turn on color filters is off. If it’s on, turn it off, or select None from the filter options.
Let me know if you need any further assistance.
Thank you.
