Background colors: Texture Paint vs Modeling - why different colors?

Support Basics & Interface
1

Both my ‘Texture Paint’ and ‘Modeling’ workspaces by default use Material Preview viewing mode.

But the background color is different. Why is that? (FWIW, I find it disorienting.)

change them to be the same or turn down world opacity and they’ll both be gray

I think they’re that way by default just to help you remember what workspace you’re in. You can set them all the same easily enough.
