Clear, Blue, Yellow, or Red original Game Boy. Please PM me if you have one in decent condition. Even in poor condition, as long as the screen works with no dead pixels.
There was also black. And green.
Just an FYI, there is no "Blue" Play it Loud brick in the U.S. However there were a couple different Blue Play-it-Loud Game Boy Pockets.
