How to Change Accent Color in Windows 10 and 11: Step-by-Step Guide

Introduction / Why Do This?

The Accent Color in Windows is the primary color used to highlight interactive interface elements: window title bar buttons, scrollbars, the taskbar, the Start menu, and some elements in applications. Changing this color is one of the fastest and most effective ways to personalize the look of the operating system, make it visually unique, and more comfortable for your eyes. This guide applies to Windows 10 and Windows 11.

After completing the steps, you will get an interface colored in your chosen color, which will improve visual perception and match your taste.

Requirements / Preparation

Before you begin, ensure that:

• You have Windows 10 (version 1903 or newer) or Windows 11 installed.
• You have local administrator rights (for the registry editor method).
• For some third-party programs, you may need to temporarily disable your antivirus.

Method 1: Standard Windows Settings (Recommended)

This is the simplest and safest method, supported by Microsoft itself.

Step 1: Open the Personalization section

Press the Win + I key combination to open Windows Settings. In the left menu, select "Personalization", and then the "Colors" tab.

Step 2: Choose an accent color

In the "Choose your accent color" section, you will see a grid of suggested colors. Click on a color you like. The system will apply it instantly to the elements you selected (see step 3).

💡 Tip: If the color you need isn't in the grid, click "Custom colors" below. A panel will open where you can define a color using RGB (Red, Green, Blue) sliders or enter a HEX code (e.g., #FF5733) directly.

Step 3: Define the application area

Below the palette, find the toggle "Show accent color on the following surfaces":

• "On the taskbar and Start menu" — the color will apply only to these elements.
• "In title bars and window borders" — the color will be applied within programs.
• "On both" — the maximum effect (recommended).

Step 4: Adjust transparency (optional)

Below, you can enable "Transparency effects" so the accent color looks more harmonious on semi-transparent backgrounds.

Method 2: Advanced Settings via Registry Editor

This method gives you full control over the color, including fine-tuning options unavailable in the interface. You edit the registry at your own risk.

Step 1: Launch the Registry Editor

Press Win + R, type regedit, and press Enter. Confirm the launch as an administrator.

Step 2: Navigate to the accent color key

In the editor, navigate to the path:

HKEY_CURRENT_USER\Control Panel\Colors

In the right pane, find the AccentColor value. Its data is a string in R G B format (e.g., 0 120 215 — the standard Windows blue).

Step 3: Change the value

Double-click AccentColor. In the "Value data" field, enter new numbers for R (red), G (green), B (blue) in the range 0 to 255, separated by a space. For example, for bright green: 57 255 20. Click OK.

Step 4: Apply the changes

Important: Changes in the registry will only take effect after you sign out and sign back in or restart your computer. Close the Registry Editor and restart your PC.

⚠️ Important: In Windows 11, there are also keys AccentColorInactive (color for inactive elements) and AccentColorMenu (menu color). You can change these similarly for fine-tuning.

Method 3: Using Third-Party Programs

For enthusiasts wanting even more flexibility (e.g., random color changes, color schemes), utilities exist.

Step 1: Choose and install a program

Popular options:

• Classic Start (free) — allows changing the accent color and other aspects of the Start menu.
• WindowBlinds (paid) — a powerful program for full Windows skinning, including colors.
• Accent Colorizer (free, from Microsoft Store) — a simple app for quick color changes.

Step 2: Configure the color in the program's interface

Launch the chosen utility. It usually provides an extended palette, the ability to use an image as a color source, or configure different colors for different elements.

Step 3: Save and apply the theme

After configuring, click "Apply" or "Save". Often, a restart or restarting Explorer (explorer.exe) is required for changes to take effect.

Verifying the Result

After applying any of the methods:

1. Look at your taskbar (buttons for running programs, notifications) — they should be colored in the new color.
2. Open any program window (e.g., Notepad) and look at the window title bar (minimize/maximize/close buttons) and title bar strip.
3. Press Win and open the Start menu — its background and accent elements (e.g., the "All apps" button) should also change color.

If the color didn't change, try restarting your computer.

Potential Issues

Problem: Nothing changed after changing the color via the registry.

Solution: Ensure you entered the RGB values correctly (0-255) and restarted your computer. Also, check if your color conflicts with Windows' dark/light mode (Settings → Personalization → Colors → Choose your mode).

Problem: The accent color is very pale or almost invisible.

Solution: In the standard settings (Method 1), try selecting a more saturated color from the suggested palette. If using the registry, increase the RGB values (closer to 255). Also, check if "Transparency effects" are enabled — they can visually "lighten" the color.

Problem: I want the color to change automatically (e.g., by time of day).

Solution: There are no built-in tools for this. Use third-party programs like WindowBlinds, which support dynamic themes, or automate registry key changes via Task Scheduler and a PowerShell script.

# Example script to change the color to green (R=0, G=255, B=0)
Set-ItemProperty -Path "HKCU:\Control Panel\Colors" -Name "AccentColor" -Value "0 255 0"
# Applying requires signing out/in or a reboot.
