The Sexual Reproduction of Color

Primary Colors.Sex.Secondary Colors. Roller Coster. It is still hard to verbally conceptualize the installation. I've got a few pictures that could make sense of what I'm doing.
Here's a very crude drawing of the piece.

Let's talk design: 

I'm going to have one black piece of wood, probably a circle. There will be three small holes in it. One of the holes has red and yellow tubing wrapped around each, they go into a tube together and orange shoots out. Another hole has Red and blue wrapped together and they go into a tube and out shoots purple. Another hole has yellow and blue wrapped together as they go into a tube green shoots out. The inspiration from a rollercoster and as the tubes go through tunnels together, their secondary colors or "babies" come out the other end.
