How can i change the default "selected tab'' color ?

[melanied]

Currently, the default color seems to be white.
Actually, i would like the tab to match the content color when selected.

For example, see the attached image.
Here, the white tab is selected so it matches the content since the default selected tab is white.

But when i select the turquoise one, it's still while but i would like to change it for turquoise as well.

I'm on VS 2019, anybody has a clue to tell me where/how to change the default color?
