How can I get this pattern?

As you can see, in this screen shot, the background of this button has a sort of funnel type multicolored look to this. I am trying to get this in PhotoShop but I cannot seem to get the perfect calculations to match this up in a 512x512 pixel square. If anyone could give me the necessary equations to figure out how these could be perfect, then that would be absolutely amazing!
