Fantastic! Play around all you want. Maybe while you are playing, notice that the 6-character string above uses two characters to represent red, two for green, and two for blue.
When it counts, it goes from 0-9 like normal, but then continues counting with a, b, c, d, e, and then f. So actually, when it says "10" above, the number it represents is 16.
Try setting the sliders for all three boxes to "16". Notice that it now says "#101010" above.
When you are done experimenting, click "Continue".
