If you take a Game Boy advanced (it will probably work with color too, but I haven't tried it yet) and insert a Gameboy game that was for the original, non-color Gameboy, (I used super Mario land 2) you can change the entire game to be tinted a certain color.
All you need to do is when you are at the screen that says Nintendo, press one of the four d-pad buttons, or all of them. Each one has a different color.
