I actually tried making it the same background initially, which ended up looking kind of weird, here is what that looks like:



It doesn't really separate out the "list container area" as a separate enough thing.

It is really most common for such list control type things to have a light colored background, in many things. For example in the standard File open dialog, notice how the "list container" control that lets you pick out of a list of things, has a light colored background:



So that's why I ended up with that light colored background, it actually seems more normal to me and kind of more typical of other "list control" UI in general.
