Help with multiple events within MC

Hey, forgive me if this is in the forum somewhere - I have searched but couldn’t find anything relevant.

My problem. I want to create a shape, lets say a red circle. On rollover, I want that red circle to change colour to blue. After rolling out, and the circle is still blue - I want to rollover again, but this time on the second rollover I want the circle to tween from blue to red (original state) and then to green. And likewise for the third rollover, green to red and then to say… yellow. Hopefully you understand what I’m trying to create. Seeing as my limit of actionscript is frame labeling and rollovers, I haven’t really got a solid idea of what I could achieve with actionscript.

I was going to try and explain what I had tried to do, but perhaps it would be better if you had a look at it.

Any help would be very much appreciated!
