Windows 11 Color filters change the color palette that Windows shows on your screen. They are a built-in accessibility setting, not a physical filter or overlay on the monitor, and their purpose is to help you tell apart items that differ only by color. Microsoft’s support documentation describes the effect in those terms, but it does not explain exactly where in the display pipeline the change is applied, and it does not promise identical results in every app or display setup.
What the filter actually changes
Color filters remap the colors Windows sends to the display. Everything on screen, including the desktop, Settings, File Explorer, and most apps, is drawn with the altered palette. Microsoft’s Windows support page states it directly: “Color filters change the color palette on the screen and can help you distinguish between things that differ only by color.” (Microsoft Support, Use color filters in Windows, applies to Windows 11 and Windows 10.)
Because the change happens to the palette rather than to the panel, nothing needs to be installed and no hardware is involved. The official instructions require only the Windows Settings app. Glasses, monitor overlays, and calibration tools are not needed to use the feature.
The filter choices
Microsoft’s accessibility guidance says Windows includes predesigned color-vision filters for deuteranopia, protanopia, and tritanopia. These are the three common forms of color-vision deficiency that the filters are designed to address, and each one reshapes the palette in a different way. (Source: Microsoft Support, Use color and contrast for accessibility in Microsoft 365, which includes Windows accessibility guidance.)
#1 Best Overall

- A BETTER READING EXPERIENCE: For busy office workers, EasyRead mode provides a more paper-like experience for when viewing lengthy documents
The current Color filters page does not list every option in the Windows 11 menu, so treat the three color-vision filters above as the documented core rather than a complete inventory, and check the menu on your own PC for the full set.
Predesigned color-vision filters
These filters are intended for people whose color perception differs from the typical pattern. Microsoft does not publish clinical outcomes or measured effectiveness for them, so the most reliable way to judge a filter is to switch between options and see whether the content you care about becomes easier to read.

The inverted filter
Inversion reverses the display colors. Microsoft’s inversion guidance gives these examples: black becomes white, red becomes turquoise, and green becomes purple. Those examples describe inversion only. They do not describe how the other filters look, because each filter uses its own palette.

The support documentation is instructional. It does not say which stage of the graphics pipeline performs the transformation, and it does not give technical behavior for HDR content, screenshots, external display arrangements, or applications that manage their own color. Do not assume the filter behaves the same way in those cases. Test them directly if they matter to your work.

No named statistic, study, or clinical result for Color filters appears in Microsoft’s official pages reviewed for this article. Treat the feature as a practical accessibility aid, not a guaranteed correction for color-vision deficiency.
How Color filters differ from nearby display settings
Several Windows 11 settings affect how the screen looks, and they are often confused with Color filters. The table below separates them by what each one changes.
Rank #4
- CURVED FOR ENHANCED ENGAGEMENT: An immersive viewing experience with a curved monitor that wraps more closely around your field of vision; It creates a wider view, enhancing depth perception and minimizing peripheral distraction
- SMOOTH PERFORMANCE FOR SEAMLESS CONTENT: Stay in the action when playing games, watching videos, or working on creative projects; The 100Hz refresh rate reduces lag and motion blur so you don't miss a thing in fast-paced moments¹
- MORE GAMING POWER: Gain the edge with optimizable game settings; Color and image contrast can be adjusted to see scenes more vividly and spot enemies hiding in the dark; Game Mode adjusts any game to fill the screen so you can view every detail²
- KEEP IT EASY ON THE EYES: Care for your eyes and stay comfortable, even during long sessions; Advanced eye comfort technology certified by TÜV reduces eye strain by minimizing blue light and reducing irritating screen flicker²
- INCREASED VERSATILITY: Connect to more; Plug devices straight into your monitor for increased flexibility, making your computing environment even more convenient
| Control | What Microsoft says it changes | Where to find it and how to tell it apart |
|---|---|---|
| Color filters | The screen’s color palette, to help distinguish content that differs only by color. | Accessibility > Color filters. Try options and inspect familiar apps. (Microsoft Support) |
| Inverted filter | Reverses display colors. Examples: black to white, red to turquoise, green to purple. | One filter choice inside Color filters, not a separate feature. (Microsoft Support) |
| Night light | Makes display colors warmer. Microsoft says it is intended to help at night. | System > Display > Night light. It is separate from Color filters. (Microsoft Support) |
| Brightness and content-adaptive brightness | Brightness changes screen luminance. Some Windows 11 PCs can also adjust brightness and contrast based on displayed content. | System > Display. Content-adaptive support depends on hardware and configuration. (Microsoft Support) |
| Dark mode | Switches supported Windows interface surfaces and apps to dark colors. | Personalization > Colors. App support varies. (Microsoft Support) |
| Contrast themes | Use distinct color combinations for interface elements to improve visibility. | Accessibility > Contrast themes. (Microsoft Support) |
| Color profiles and calibration | Color management: add or remove profiles, set defaults for connected displays, and access calibration. | Display color management. Not the Color filters toggle. (Microsoft Support) |
How to turn Color filters on
- Press the Windows logo key + U to open Accessibility settings, or select Start > Settings > Accessibility.
- Select Color filters, then turn on the Color filters switch.
- Choose a filter from the list and compare it with the others. Keep the one that makes your most-used content easiest to read.
- Optional: turn on the keyboard shortcut option in the Color filters settings. Once enabled, Windows logo key + Ctrl + C toggles the filters on and off. Microsoft documents this shortcut on its Make Windows easier to see page.
Checking the result in the apps you use
Microsoft recommends trying the available options and checking the apps you use most, because the changed palette can look different from one piece of content to another. Before settling on a filter, check the following:
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Charts, graphs, and status indicators, where color often carries the meaning.
- Text and buttons in your main apps, including web pages in your browser.
- Photos and video, which may look noticeably different from the originals.
- Any app you work in every day, since its own color choices may interact with the filter.
When a different setting fits better
If the problem is that text or controls blend into the background, Contrast themes are a better first test than a color filter, because they change the contrast between interface elements rather than the overall palette. If the screen feels too bright or too warm at night, adjust brightness or Night light in System > Display instead of changing the color filter. Use Color profiles and calibration only when you are managing how a specific monitor reproduces color, not when you are adjusting how Windows presents the interface.
