Groups & Roles

Groups & Roles

Hi Guys, I need some help with this diagram below:
In my case User 5 has accounts and opportunities that are ONLY applicable to the RED group and has different account and opportunities that are ONLY applicable to the GREEN group. I can't figure how to limit visibility of the Accounts/Opps to the groups that need to know. I don't want the green guys to see what the red guys are doing.
Help!

Tom
