Windows 10 includes Color Filters as part of the Ease of Access system. They improve usability of the operating system for people with various vision issues. Color filters work at the system level, so all installed software including third-party apps and built-in Windows apps will follow them. You can enable color filters with a hotkey.
The Color Filters feature we are going to use today is available in Windows 10 starting with build 16215. Tip: See how to find the Windows 10 build number you are running.
