Changing interface colors

Good morning everyone,
I’ve been trying to change the cubase interface into something lighter, and a little more like the old versions of Cubase. However, it seems it is not possible to change the interface background and a few other elements from the preferences window. Is there any way I can make those lighter too?

Thanks in advance.

Edit: I’d also like to know why my screenshot doesn’t appear as an image. Sorry if it is a dumb question, I’m still new to this forum…
