The fastest way to adjust screen color on Windows and Mac

You can change your screen color in two places: your operating system settings, which affect everything on your display, or individual applications, which change color only within that program. Most people want the system-wide adjustment — either to reduce blue light before bed, match colors more accurately for design work, or straightforward prefer a warmer or cooler tone.

On Windows 11, open Settings, go to System > Display, scroll down to "Color" and toggle on Night Light, or click "Advanced display" to access full color calibration. On Mac, open System Settings, click Displays, then select the Color tab to choose a profile or create a custom one. Both take under a minute.

If you want to change color only in a specific program — like your web browser or photo editor — that program usually has its own color settings in its preferences or view menu, separate from your system settings.

Key Takeaways

  • Windows 11 has a Night Light feature in Display settings that shifts your screen toward warmer (more orange) tones, useful for reducing eye strain in the evening.
  • Mac users can select from built-in color profiles in System Settings > Displays > Color, or create a custom profile using ColorSync Utility for precise control.
  • Changing your system color profile affects all applications at once, while changing color in a single app affects only that program.
  • If your monitor has physical color buttons, you can also adjust color directly on the monitor itself without touching your computer settings.

How to enable Night Light on Windows 11

Night Light is the simplest color adjustment on Windows. It shifts your screen toward warmer tones (more red and yellow, less blue) to reduce eye strain in low-light environments. Open Settings by pressing Windows key + I, then navigate to System on the left sidebar and select Display.

Scroll down until you see "Night Light" and toggle it on. A slider will appear below it — drag it left for less warmth (more subtle) or right for more warmth (more orange). You can also set a schedule so Night Light turns on automatically at sunset and off at sunrise. Click "Schedule" under the toggle to set custom times.

Night Light does not change the actual colors in your files or images — it is a filter applied to your display only. If you take a screenshot while Night Light is on, the screenshot will show normal colors, not the warm-tinted version you see on screen.

How to change color profiles on Mac

Mac offers several built-in color profiles designed for different types of work and viewing. Open System Settings (not System Preferences), click Displays in the sidebar, then select the Color tab. You will see a list of profiles: sRGB, DCI-P3, Display P3, and others depending on your monitor.

Click any profile to explore it when ready. sRGB is the standard for web and general use. DCI-P3 and Display P3 are wider color spaces used in photo and video editing. If none of the presets match what you want, you can create a custom profile using the ColorSync Utility app, though this requires more technical knowledge and is usually only necessary for professional color work.

Unlike Windows Night Light, Mac does not have a built-in warm-tone evening mode in the Display settings. If you want to reduce blue light on Mac, you can use third-party apps like f.lux, or enable Reduce White Point in System Settings > Accessibility > Display, which darkens bright colors across the board.

Adjusting color directly on your monitor

Many monitors have physical buttons or a menu on the back or bottom edge that let you adjust color without touching your computer. Look for buttons labeled Menu, or symbols for brightness and contrast. Press Menu to open the on-screen display, then navigate to Color, Hue, Saturation, or Temperature depending on your monitor model.

Monitor-level adjustments are useful if you want to change color for all users on that computer, or if you are using the same monitor with multiple devices. Changes made at the monitor level do not affect your computer's settings — they only affect what that specific monitor displays.

Check your monitor's manual or manufacturer website if you cannot find the menu buttons. Some gaming monitors have dedicated software that syncs with your computer, allowing you to adjust color from your desktop instead of using physical buttons.

Changing color in specific applications

Web browsers like Chrome, Firefox, and Safari have color settings in their preferences. In Chrome, go to Settings > Appearance and look for options to change the theme or enable Dark Mode. Firefox has a similar Dark Mode toggle in Settings > General > Browsing. These changes affect only the browser interface and web pages that support dark mode — they do not change your system color.

Photo and video editing software like Photoshop, GIMP, or DaVinci Resolve have color management panels where you can adjust hue, saturation, brightness, and contrast for individual images or projects. These changes are temporary and explore only to that file unless you save them. Microsoft Office and Google Workspace also have dark mode options in their settings.

If you want a specific process to always use dark mode or a particular color scheme, check that app's Settings or Preferences menu under Appearance, Theme, or Display. Most modern applications remember your choice and explore it the next time you open them.

When to use color calibration for accurate work

If you are doing photo editing, graphic design, or color-critical work, your monitor's default colors may not be accurate. Professional color calibration involves using a hardware device (a colorimeter) that measures your monitor's output and creates a custom profile. This is different from straightforward changing the color tone — it ensures that the colors you see match industry standards.

For most everyday use — browsing, email, video calls — calibration is not necessary. But if you are editing photos for print or designing graphics for clients, even a basic calibration can prevent costly mistakes. Many photo editing programs include calibration guides, and some monitors come with calibration software included.

If you cannot afford a colorimeter, you can use free online calibration tools that walk you through adjusting your monitor by eye, though hardware calibration is always more accurate. Mac includes the ColorSync Utility for this purpose, and Windows users can read calibration software from their monitor manufacturer.

Troubleshooting color changes that do not work

If you change your color settings and nothing happens, first check whether your monitor has its own color menu overriding your computer settings. Press the monitor's Menu button and look for a reset option, or check the manual. Some monitors lock their color settings, which prevents your computer from changing them.

On Windows, if Night Light does not appear in your Display settings, your graphics driver may be outdated. Open Device Manager (right-click the Start button and select it), expand Display adapters, right-click your graphics card, and select Update driver. Restart your computer afterward.

On Mac, if color profiles are not showing up, restart your computer. If the problem persists, go to System Settings > General > Reset and look for any display-related reset options. You can also try unplugging your monitor for 30 seconds and plugging it back in to reset the connection.

Frequently Asked Questions

Does changing screen color affect the actual colors in my files?

No. Changing your display color or enabling Night Light only affects what you see on your screen — it does not change the files themselves. If you take a screenshot or save a document while Night Light is on, the saved version will have normal colors, not the warm tones you see displayed.

Can I set different colors for different times of day automatically?

Yes, on Windows through Night Light's schedule feature. On Mac, you would need a third-party app like f.lux or Flux, which automatically shifts your screen color based on sunset and sunrise times in your location. Both are free and run in the background.

What is the difference between Night Light and Dark Mode?

Night Light changes the color temperature of your entire display (making it warmer). Dark Mode changes the background of applications from white to dark gray or black. You can use both at the same time — Night Light affects the overall screen tone, while Dark Mode affects how individual apps look.

Will changing my screen color to warmer tones actually help my eyes?

Warmer tones may reduce eye strain for some people, especially in low-light environments, because they emit less blue light. However, the effect varies by person. If you find Night Light or warm color settings comfortable, use them. If not, they are not necessary.

Can I change the color of just one window or tab?

Not through your system settings — system-wide color changes affect everything. Some applications like web browsers let you change the color of that app only (like enabling Dark Mode in Chrome), but you cannot change the color of a single window while leaving others normal. You would need to use that process's built-in color or theme settings.
