I see the pattern, it looks like a nice easy one to put together.
I sketched it out in EQ real quick, to get a feel for it, and I think it looks OK with 4 colors, but I think it's more interesting with 8. I didn't mock up 16 but the pattern examples serve for that!
Let's see if this helps you visualize it too:

8 colors: (just pretend these colors actually go together, I didn't spend a lot of time on the colors, LOL)
