How to Change Color on Computer Screen: A Complete Guide for Windows and macOS

To change the colors on your computer screen, navigate to your operating system's personalization settings. On Windows 11, go to Settings > Personalization > Colors to adjust themes and accents. On macOS, open System Settings > Appearance. These menus allow you to toggle between Light and Dark modes, select accent colors, and apply accessibility filters.

Changing the color profile or visual theme of your computer screen is more than a simple aesthetic choice; it is a fundamental aspect of digital ergonomics, accessibility, and professional accuracy. Whether you are a graphic designer requiring precise color reproduction, a night-owl looking to reduce eye strain, or a user with color vision deficiency needing high-contrast filters, modern operating systems offer deep levels of customization. As of 2026, both Windows and macOS have refined these interfaces to be more intuitive while adding advanced features like AI-driven color matching and enhanced High Dynamic Range (HDR) controls.

Understanding the Layers of Screen Color Customization

Before diving into the specific steps for each operating system, it is important to distinguish between the different "types" of color changes you can perform. Users often confuse system themes with color calibration, but they serve very different purposes.

1. System Themes and Accents: This refers to the "skin" of your operating system. It changes the color of window borders, the taskbar, the Start menu, and buttons. This is primarily for personalization and reducing glare (via Dark Mode).
2. Color Calibration and Profiles: This affects how the monitor interprets data to display specific hues. If your screen looks "too blue" or "too yellow," or if your printed photos don't match your screen, you are dealing with color profiles (ICC profiles).
3. Accessibility Filters: These are designed for users with visual impairments. They can invert colors, turn the screen grayscale, or apply specific filters to assist those with Protanopia (red-blind), Deuteranopia (green-blind), or Tritanopia (blue-blind).
4. Blue Light Filters: Known as "Night Light" or "Night Shift," these features shift the color temperature of your display toward the warmer end of the spectrum to reduce blue light exposure in the evening.

How to Change Colors on Windows 11

Windows 11 offers a robust "Personalization" engine that allows for granular control over the interface. By 2026, Microsoft has integrated these settings more deeply with the "Mica" material design, which allows desktop background colors to subtly bleed through active windows.

Adjusting the System Mode and Accent Colors

The most common way to change colors is through the Personalization menu.

• Step 1: Right-click any empty space on your desktop and select Personalize. Alternatively, press Windows Key + I and click on Personalization in the left sidebar.
• Step 2: Click on Colors.
• Step 3: Under Choose your mode, select between Light, Dark, or Custom.
  
  
  • Light Mode provides a crisp, high-brightness look suitable for well-lit rooms.
  • Dark Mode switches the background of menus and apps to dark grays or blacks, which is easier on the eyes in low-light environments.
  • Custom Mode allows you to set the Windows mode (taskbar/Start menu) to Dark while keeping apps in Light mode, or vice versa.
• Step 4: Toggle Transparency effects to "On" if you want windows and surfaces to appear slightly translucent.
• Step 5: Choose your Accent color. You can select Automatic to let Windows pick a color based on your wallpaper, or Manual to select from a grid of colors.
• Step 6: Scroll down to "Show accent color on Start and taskbar" and "Show accent color on title bars and windows borders" to apply your chosen color to the UI elements.

Implementing Color Filters for Accessibility

If you need to change the colors for better visibility or color blindness, Windows provides a dedicated suite of tools.

• Navigate to Settings > Accessibility > Color filters.
• Switch the Color filters toggle to On.
• Choose from the available options: Red-green (green weak, Deuteranopia), Red-green (red weak, Protanopia), Blue-yellow (Tritanopia), Grayscale, or Inverted.
• You can also enable a keyboard shortcut (Windows Key + Control + C) to toggle these filters on and off instantly.

How to Change Colors on macOS (Sequoia and Later)

Apple’s macOS has long been the standard for color accuracy, and its customization options are streamlined for ease of use. In 2026, macOS Sequoia continues to offer "Appearance" settings that affect the entire ecosystem of native apps.

Changing the Appearance and Accent Hues

On a Mac, the primary color settings are located within the System Settings app.

• Step 1: Click the Apple Menu () in the top-left corner and select System Settings.
• Step 2: Scroll down the sidebar and click Appearance.
• Step 3: At the top, select your mode: Light, Dark, or Auto. The "Auto" setting is particularly useful as it transitions your screen from light to dark based on the local sunset and sunrise times.
• Step 4: Select an Accent color. macOS provides several presets (Blue, Purple, Pink, Red, Orange, Yellow, Green, and Graphite). Selecting the multi-colored icon allows the system to pull an accent color from your current wallpaper.
• Step 5: Choose a Highlight color. This determines the color you see when you click and drag over text. By default, it follows the accent color, but you can set it to a specific shade if you prefer more contrast.

Managing Display Profiles for Color Accuracy

For professionals, changing the color "profile" is more important than the accent color. This ensures that the colors displayed on the screen meet industry standards like sRGB or P3.

• Go to System Settings > Displays.
• Next to Color Profile, click the drop-down menu.
• You will see a list of available profiles. For most users, Color LCD (the default) is best. However, if you are editing video for cinema, you might select Display P3 or Photography (sRGB).
• If your screen looks incorrect, you can click Customize... and use the Display Calibrator Assistant to manually adjust the white point and gamma of your screen.

Adjusting Color Temperature with Blue Light Filters

Both Windows and macOS include features to change the "warmth" of the screen. High levels of blue light in the evening can disrupt circadian rhythms by suppressing melatonin production. By shifting the screen toward the amber or yellow spectrum, you can reduce eye fatigue.

Windows Night Light

1. Go to Settings > System > Display.
2. Click on Night light.
3. Click Turn on now to activate it immediately.
4. Use the Strength slider to choose how much blue light to filter out. A higher strength results in a more orange-tinted screen.
5. You can schedule this to turn on automatically at sunset or during specific hours.

macOS Night Shift

1. Go to System Settings > Displays.
2. Click the Night Shift... button.
3. Set a Schedule (e.g., Sunset to Sunrise).
4. Adjust the Color Temperature slider. Moving it toward "Warmer" increases the yellow tint, which is recommended for nighttime use.

Using High Dynamic Range (HDR) for Vibrant Colors

As of 2026, most mid-range and high-end monitors support HDR. Enabling this changes how colors are processed, allowing for deeper blacks and much brighter highlights.

On Windows 11, you can find this under Settings > System > Display > HDR. If your monitor supports it, you can toggle Use HDR to "On." Windows also features "Auto HDR," which uses artificial intelligence to upgrade the color range of older, non-HDR games and applications.

On macOS, HDR is handled automatically on MacBook Pro models with Liquid Retina XDR displays. However, for external monitors, you can manage this under System Settings > Displays, where you can toggle High Dynamic Range if the connected display is compatible.

Troubleshooting Common Color Problems

Sometimes, you might want to change your screen colors because something has gone wrong. Here are three common issues and how to resolve them:

1. The Screen is Grayscale (Black and White)

This is usually caused by an accidental keyboard shortcut that turned on an accessibility filter.

• Windows: Press Windows Key + Control + C. If that doesn't work, go to Settings > Accessibility > Color filters and turn them off.
• macOS: Go to System Settings > Accessibility > Display and ensure "Color Filters" is toggled off.

2. Colors Look Washed Out or "Faded"

This often happens when HDR is enabled on a monitor that doesn't have the peak brightness to support it effectively.

• Try disabling HDR in your system settings to see if the saturation returns to normal.
• Check your monitor's physical "OSD" (On-Screen Display) menu via the buttons on the monitor itself. Ensure the "Saturation" or "Color Temp" hasn't been set to a low value.

3. The Screen has a Yellow or Orange Tint

This is almost always due to Night Light or Night Shift.

• Check your display settings to see if a schedule is active. If you are a designer, you should turn these features off entirely while working to ensure you are seeing accurate colors.

Frequently Asked Questions

Does changing my screen to Dark Mode save battery life?

On laptops with OLED screens, Dark Mode can significantly save battery life because OLED pixels are individually lit; black pixels are essentially "off" and consume no power. On standard LCD or LED-backlit screens, Dark Mode has a negligible effect on battery life because the backlight remains on regardless of the color shown on the screen.

Can I change the color of just one specific window?

Neither Windows nor macOS currently supports changing the title bar color of a single specific application natively. Accent colors are generally applied system-wide. However, some individual applications (like Chrome, Spotify, or Microsoft Office) have their own internal "Themes" or "Appearance" settings that override the system defaults.

What is the difference between "Accent Color" and "Highlight Color" on a Mac?

The Accent Color changes the color of UI elements like radio buttons, dropdown menus, and sidebar icons. The Highlight Color is specifically for the background of text you have selected with your cursor. While they are often set to be the same, separating them can help with visibility if you prefer a bright accent but a subtle text highlight.

Why do my screen colors look different after a driver update?

Graphics driver updates (from NVIDIA, AMD, or Intel) sometimes reset color settings to factory defaults. Additionally, these drivers often include their own control panels (like the NVIDIA Control Panel) which can override Windows settings. If your colors look wrong after an update, check the "Desktop Color Settings" within your GPU's specific software.

How do I get my monitor to show "true" colors for printing?

To achieve color accuracy between your screen and a printer, you must use a hardware colorimeter (like a Spyder or X-Rite device). This tool sits on your screen and measures the output, creating a custom ICC Profile that tells your computer exactly how to adjust its output to reach industry-standard accuracy.

Practical Recommendation

If you spend more than four hours a day in front of a computer, the best configuration for eye health and productivity is a hybrid approach. Use Dark Mode for your system theme to reduce overall glare, but keep your document editors (like Word or Google Docs) in Light Mode (black text on white background), as studies suggest this is easier for the brain to process during long reading sessions. Additionally, always schedule Night Light or Night Shift to begin at least two hours before you plan to sleep to help maintain a healthy sleep cycle.
