Dark/High Contrast Settings

Hi everyone,
I've used WindowBlinds extensively in the past, but now with the color change options of Aero, I really don't have a need for it anymore. The problem is, however, that I can't get some things dark like before. For example, Start Menu, folder backgrounds, and the page in Word are all white and I'd like to make them high-contrast while keeping Aero. Does anyone know a way to do this? I've tried experimenting with the advanced appearance settings without result. On a side note, I've also been unable to change the logon screen, even with all the tools and suggestions I've found on this forum.
Thanks!

Thanks! Yeah, I want a way (if it's possible) to have a high-contrast aero theme. I just want to get rid of as many white backgrounds as possible.
Thanks for the reply!
