To enable color filters in Windows, open Settings with Windows I, go to Accessibility (or Ease of Access in Windows 10), select Color Filters under Vision, then toggle "Use color filters" on; next, choose a filter type from the dropdown—1. Grayscale, 2. Inverted, 3. Grayscale Inverted, 4. Deuteranopia, 5. Protanopia, or 6. Tritanopia—based on your needs; optionally, enable the "Allow the shortcut key to toggle filter on or off" option to use Windows Ctrl C for quick toggling, and test the filter in real-world scenarios for best results, as it applies system-wide across all monitors and apps to improve color distinction without altering actual screen emissions.
Color filters in Windows can help users with color vision deficiencies (like color blindness) better distinguish between colors on the screen. This feature is especially useful for those who have trouble differentiating reds, greens, or blues. Here's how to enable and use color filters in Windows 10 and Windows 11.

How to Turn On Color Filters
Open Settings
PressWindows I
to open the Settings app.-
Go to Accessibility (Ease of Access in older versions)
In Windows 11, click on Accessibility in the left sidebar. In Windows 10, go to Ease of Access. Navigate to Color Filters
Scroll down to the Vision section and click on Color filters (in Windows 11) or Color filters under the "Display" category (in Windows 10).-
Turn on Color Filters
Toggle the switch labeled "Use color filters" to On.
Choose the Right Filter Type
Once enabled, you can select a filter that best suits your needs from the dropdown menu:
- Grayscale – Removes all color from the screen, useful for reducing visual distractions.
- Inverted – Reverses all colors (light becomes dark, colors shift).
- Grayscale Inverted – Combines grayscale with inversion.
- Deuteranopia – Designed for red-green color blindness (most common type, difficulty with green).
- Protanopia – Adjusts colors for those with difficulty seeing red.
- Tritanopia – Helps those with blue-yellow color vision deficiency.
Try each filter briefly to see which one improves your screen readability the most.
Use a Keyboard Shortcut (Optional)
Windows allows you to quickly turn color filters on or off:
- Press
Windows Ctrl C
to toggle the last used color filter.
Note: This shortcut must be enabled manually. In the Color filters settings, make sure the option "Allow the shortcut key to toggle filter on or off" is turned on. Without this, the
Win Ctrl C
shortcut won’t work.
Tips for Best Results
- Test filters in real scenarios (e.g., websites, spreadsheets, maps) to see which works best.
- The filter applies system-wide, so it affects all apps and the desktop.
- If you're using multiple monitors, the filter applies to all displays.
- Some users may find the filter makes certain color-coded information harder to read at first—give it a few minutes to adjust.
Color filters won’t change the actual colors emitted by your screen but instead overlay a software-based adjustment. It’s a simple yet effective tool for improving accessibility.
Basically, just turn it on, pick the right filter, and use the keyboard shortcut if you want quick access. Doesn’t fix color blindness, but can definitely help make things clearer.
