I have several Baggallini bags (Amazon has the best prices!).
I just did a quick check on a couple of mine, and the interior looks like a lightr shade of the bag color.
They are lightweight - and handy when you don't need to carry a lot of "stuff."
I don't use them very often - typically I'll use them if I'm going someplace that a fanny pack won't work ... e.g. out to lunch or to a meeting - and just need my phone, ID and credit cards
