i'm trying to make a short flash animation that illustrates what happens when
certain colors overlap each other (red, green, and blue). unfortunately, my
flash intelligence only goes as far as making things move around and other
simple actions. is there a way that i can make colors change as another object
moves on top of an object of a different color? (i.e. i have a red circle and
as the green circle starts overlapping it, the overlapped section becomes
yellow). any help is appreciated, thanks.

create three movie clips (one red, one blue, one green) on three layers. Make your background black. Set the Blend mode of each clip to "Add".
