Change the Windows 10 Active/Inactive Window Color


If you’re one of those people that stay up into the wee hours of the night; if you prefer to have less eye strain with flat interface colors that have just the right amount of contrast; or if you’re looking to tinker with your Windows 10 box – this is the tutorial for you.

Registry Edits

Open Regedit and navigate to the following key:


Create a new key by right-clicking and selecting New > DWORD (32-bit) Value and name it AccentColorInactive.

You can now double click AccentColorInactive and AccentColor to edit their values. They are in hexidecimal format but RGB is BGR. So 001122 would be 221100.

I like to use the following values:

Key Name New Value
AccentColorInactive 333333
AccentColor -212121

This creates a flat black appearance for inactive windows and active windows will have a high contrast black title bar – making them easy to identify.
