You can change the color of the buttons and backgrounds.
I use cyan.darker() for the background. green.darker() for the buttons. white
for the font. The only exception is that you can't use the default background color or the
foreground color. You can also change the image icon if you like but you have to
name it mill.jpg and submit it
