I'm actually very curious on how they build in the color picker into the site to designate the site's colors. Anyone have any knowledge on this?

Sure, it's an input type="color" with some css applied to it. On webkit, it becomes a picker, on other browsers, just a text input.

When it is changed, we loop through various elements and change their background color. The way the themes are generated is a little more complicated, but I don't think that's what you're asking about.

Yeah, I am pretty sure that you're correct.. This was a new input to me (<input type=color />) - learn something new everyday.
