If you want those complex flash patterns I would suggest you begin your quest by learning to program a micro controller.
I second what Sceadwian says. What do you want this for? Are you planning to put it in a car? Some people have valid reasons to put something like this in their car (volly fire/EMS with proper permit) but if you don't have a proper permit and reason, don't put a red and blue light in your car.
Orange/amber lights are more legal in most areas, but you still cannot drive with them on. I have an amber light simalar to that in the back window of our car. I just used it yesterday when I had to stop in the middle of the road, in the dark, in the rain, and drag a fallen tree off the road.
