I have searched google and the forums for this topic but I cannot put together a good search phrase. Any links or suggestions would be helpful.

I have a program that generates multiple circles that need to be semi-transparent (50% alpha). The circles will overlap in places, and I need those overlapping areas to continue to be 50% transparent. Obviously the default behavior is for the overlapped areas to become MORE than 50%.

I have tried putting these circles in a container together and setting that containers alpha to 50%, but the default behavior still exists. Any suggestions?
