This is what I see when I click my applications menu from the panel.
Yes, but after adding the ppa and updating & upgrading, nothing downloaded so I guess I had the newest version already?
This bug describes what I see: https://bugs.launchpad.net/light-themes/+bug/1047736 and mentioned above with images.
Anyway, I don't understand the OP's problem.
Maybe there's some confusion between the window manager theme and the regular theme.
Because OP writes, "Sorry, actually all of the menus in all programs ("File", "Tools", etc) are white when clicked, except for when I right click on the title bar, those are dark."
If that is so, OP should try to pick a window manager theme that closest resembles Ambiance.

I've changed all three, the openbox window border, the icon theme, and the widget to ambiance.
I have followed the instructions in this link (http://maketecheasier.com/theme-up-lubuntu/2011/02/11) perfectly but my results are still the same. All white menus, panel menu is white, and all menus for every application are white. Right click has a white menu also.
The bug report says "When I use Ambiance theme, in gtk3 apps like gedit , the context menu (mouse right click menu) appears to be dark background and light text. While in gtk2 apps like firefox and chrome, the context menu appears to be light background and black text..."
But I have no dark menus at all like this bug reporter.
Aha! Problem solved.
I was using the "light themes" package from synaptic and that did not work. Then I tried the "ambiance 12.04" package from ravefinity and that did not work either.
Then I tried the "ambiance 11.04" package from ravefinity and it works like a charm! All menus looks as they should. See link and choose the "Ubuntu 11.04 or older" if you're having the same problem as me:
Seems I was a bit hasty in thinking my problems were totally solved. Now certain applications and popup notifications are white with white text and I can't read them. Is there any way to fix this?
