I'm hopeless

I have been defeated by CS3. I spent all my time learning AS3, but I can’t apply a simple color tween to a circle. I know, in theory, that I should create a group (check), create a keyframe (check), apply a motion tween between the keyframe and the start of the timeline (check), and alter the color of the group in the keyframe (problem).

I have no idea how to alter the color of a group without double-clicking it and changing the colors manually, and that just doesn’t work. Is there a color transform tool I’m missing? Thanks.
