Windows Color Filters for Easier Reading
Windows can shift colors, raise contrast, and turn the screen grayscale for easier reading. Useful for color blindness, glare, and tired eyes.

Step 1. Open Accessibility settings
Click the Start button, then the gear icon for Settings. In the list on the left, click Accessibility. This is the section that holds every vision, hearing, and mobility setting in Windows.
Step 2. Turn on Color filters and pick one
Click Color filters, then switch the top toggle on. Choose from the list: Red-green, Green-red, Blue-yellow, Grayscale, Inverted, or Grayscale inverted. The screen changes at once so you can judge it.
Quick Tip
The colored wheel shown on the settings page is the fastest way to compare. Watch how the segments separate as you switch filters.
Step 3. Learn the on and off shortcut
Hold the Windows key and Ctrl together, then press C. That switches your chosen filter on and off. Practice it twice now so you can undo any change without hunting through Settings.
Step 4. Try a contrast theme if color is not enough
Go back to Accessibility and click Contrast themes. Pick one from the list, such as Aquatic or Desert, then click Apply. The whole of Windows changes to strong color pairings. To undo it, choose None and Apply again.
Warning
A contrast theme changes how websites and programs look, and a few older programs handle it poorly. If something becomes unreadable, set the theme back to None.
Step 5. Enlarge text separately
In Accessibility, click Text size and drag the slider right until the sample line is comfortable, then click Apply. This changes text only and leaves colors alone. Many people need this more than a filter.
Step 6. Live with your choice for a few days
Keep the setting for two or three days before deciding. Eyes adjust, and a change that looks strange in the first minute often reads better by the second evening. Change one thing at a time so you know what helped.
Quick Tip
Quick Tip: On the same Accessibility page, Mouse pointer and touch lets you make the pointer bigger and change its color. A large black or yellow pointer is much easier to find on a busy screen.
Windows has a group of display settings built for eyes that struggle with the standard screen. They are grouped under Accessibility, and none of them cost anything or change your files.
Color filters adjust the colors the screen sends out. Windows includes filters for the three common types of color blindness: red-green, another form of red-green, and blue-yellow. If charts and colored buttons have always been hard to read, one of these can make them separate clearly for the first time.
Two filters help people with no color vision problem at all. Grayscale removes color entirely, which reduces glare and can make text steadier if your eyes tire in the evening. Inverted turns light backgrounds dark, which some people find calmer in a dim room.
Contrast themes are a separate setting. They are stronger than filters, replacing the colors of buttons, menus, and text with high-contrast combinations across all of Windows. Black text on white, or yellow on black, are the common choices for low vision.
You can turn color filters on and off with one shortcut: hold the Windows key and the Ctrl key, then press C. Being able to flip it back quickly is what makes it worth trying. Nothing here is permanent, so there is no risk in testing each option for a minute.
If text is the real problem rather than color, the separate Text size slider in the same Accessibility area may serve you better. Try that first, then add a filter if it is still hard.
