Type a color name or a hexadecimal value into the first textbox and click "Change Background" to view
it as the background color. Click "Random Background" to view a random color and see its hex value in
the textbox below. "Change Constantly" will make a new, random background color at the defined interval,
and "Stop!" will stop the interval. [Do not click "Change Constantly" more than once without
clicking "Stop!" first or the script will be uncontrollable.] None of the background colors are predefined,
they are selected randomly.
