I actually was going to point out that less saturated colors get... well, maybe not more dramatic, but in-my-opinion-"better" themes. For example, with this one, any but 'complementary' are almost usable http://rriepe.github.io/1pxdeep/#e9ede4

Also, anybody that's using this should be sure to add a rule like

    input { outline: none}

or it completely ruins the whole 1pxdeep theme with OS-defined outlines on clicked buttons. On the demo, this may not work for the main "Scheme now" button, but

    #change_color { outline: none }

will.
