How to change color of busy screen in soft center?

Depends on theme background colour.
System preferences -> appearance
Example.

No, that's not what I'm talking about. When it's busy, there's going to be a white screen with a circle in the center.

Unable to reproduce the circle image.
What does 'when loading or busy' mean, please describe steps to reproduce.
Are you trying to installing something, search or is it on startup?

That screen is there whenever it's searching something. Since my computer is rather slow, that screen is displayed for a significant amount of time. On a faster computer, all searches might happen so quickly, the screen isn't even displayed. When I start the center and there is something in the search field left over from last time, it starts searching and the white screen is displayed for the first time. Whenever I search for something, the screen is displayed while it's searching.

In addition, there is a smaller white screen with a circle displayed while the screenshot is loading, when I click on "more info." I'd like to change the color of that as well.

Not resolved.

Maybe submit an idea there about colour change.
