Here’s how to change the taskbar color in Windows 10:

Why Can’t I Change the Color of My Taskbar?

If you can’t change the taskbar color in Windows 10, first make sure you have fully updated Windows. To change the taskbar color, you need to have the Windows 10 1903 feature update or newer. If you’re fully up to date, you need to make sure you set Choose Your Color to Custom and set Windows Mode to Dark. You can set App Mode to either Light or Dark, but you won’t be able to change the color of the taskbar if you’ve set Windows Mode to Light. If the Start, taskbar, and action center box in your color settings are grayed out, it’s usually because Windows Mode is on the Light setting.

Why Has My Taskbar Changed Color in Windows 10?

If you’ve noticed your taskbar color changed in Windows 10, you probably switched from dark mode to light mode. When you change between those two modes, the taskbar will automatically change colors. When the 1903 feature update arrived, introducing the ability to customize your taskbar color, it may have altered automatically at that time as well. When you navigate to Settings > Personalization > Color, you can choose your accent color or allow Windows 10 to select an accent color from your background. If you have that box checked, then the taskbar may change color automatically from time to time. It will also change color whenever you switch to a new background image, especially if the color it was using before is no longer present in the current background. If you want to go back to the old taskbar color, you can choose the custom color option from the colors menu and manually set the old color. When you set the color manually, the taskbar color will stay that color until you choose to change it or until another feature update alters Windows settings.
