Programming help needed

Hi, this is my first post here and my question is pretty specific.

I am doing a gameshow setting with two teams, they have buttons to press for each question. I want to trigger a color change when a button is pressed, but so that only the light representing his team changes.

So, Two lists, one for team 1 and one for team 2, but if team 1 presses first, and team 2 presses right after, team 2's colour does not change. Any ideas on how to program this? I'm on a full hog 3
