Insanely cool. Thanks.

Some suggestions:

I would prefer a triangle-in-a-color-wheel arrangement for the color picker.

One nice addition too would be a complementary color generator with the same saturation-luminance.

Another would be having the #rrggbb color so it could be easily copied and pasted between settings.

But swill, as it is, it's awesome. Thank you very much!
