i have a mackbook pro hooked up to an apple LED cinema display.

every time the screensaver goes off, the color profile becomes faded and looks pastey white. i have to constantly open display preferences and select my color profile for it to snap back to a normal clear display.

any ideas on how I can fix this?

I get this behavior on my G5/23" Cinema Display regularly.
Do you happen to have a hot corner defined to manually activate the screensaver? If you do, you can try moving your cursor to that corner to activate the screensaver, then quickly deactivate it by moving the cursor again. This usually snaps my Cinema Display back to the correct look. Of course, I'm on a G5, but I suspect it will still work for an MBP.

As for why this happens and how you can stop it...

Yeah I've tried what you said before and it works. Not consistently but it works. Effectively I can go to the corner and mess up my display or correct it by just trying over and over. I heard this was a widespread bug though in the apple support forums. So I'll wait for Apple to fix it (in 2011).

Good luck on that wait. My G5 is an old original 2x2 machine and it's had this glitch since the day after it first came out of the box. Obviously, fixing it isn't a priority.
