Junction box

I have a light I'm trying to install with 2 black, 2 white, 2 red, 1 yellow all stripped, and 1 green not stripped. The light switch connected only has 1 red and 1 yellow attached. Yellow on top and red on the bottom. All the switches in this unit are connected this way. What do I need to connect to the fixture to allow it to work? Anyone?

I pulled another pre-existing light and there is the yellow connected with the white, and the black only. Red is nowhere but on the switch.
