'How to set background color in IntelliJ for all panels

I'm trying to customize the colors of my scheme but I'm not getting the result I want on Intelli J.

I would like each panel to be the same shade of color and opacity. As you can see in the image, I would like the terminal and editor to be the same as the panel on the top left (empty project)

enter image description here

Do you know if this is possible? thank you all.
