Changing colour of header bar

[harryray2]

I've just switched to Win 11, and the bar at the top (that says Everything, just above the menu bar) is now white, as opposed to Blue.
I can't remember how to switch the colour of the bar?

The problem with it being white is that it sometimes merges in with any white in the background.

Thanks

The window frame color/theme is controlled by the OS, not Everything.

Please try changing your Windows title bar colors in your OS settings.
Right-click desktop -> Personalize -> Colors -> Show accent color on title bars and window borders.
Select a different accent color.
