Have moving circle change text color as it passes.

Hi!

I'm working on a comp where a black circle passes over a black font logo and a white font tag line. When the circle passes the text, I would like only that portion of the text to be seen through the circle, but in a different color. Does anyone know how to do this, or can point in me in the direction of where I can read up on that technique? Please see the Dropbox link below for a mock up of what I'm trying to do.

The Logo is a PNG file, but I do have access to the original AI file. The tag line is text created within AE.

Thank you!

- Miguel
