Description of problem:
If a user has multiple repos available for sync, the backgrounds colors for each repo alternate white and gray. However, when syncing, the "empty" sync bar is white. This is fine on the divs with the gray background, but on the divs with the white background, it is somewhat confusing initially, especially when user is syncing multiple repos at the same time.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1.  Add/enable a RH repo 
2.  Add a third party repo

The empty status bar in a repo with a white background is white... white on white - invisible.

Something with a little better designated status bar.
