 	Check the archives for the DVD image I posted awhile back.  It's 
got colorbars, some gamma correction, and some other test patterns on it. 
It's guaranteed to be as accurate as anything else you might find on 

 	At the very least you could compare it to the colors you get 
playing it through a DVD player.
