If you check with that image, the color of the bolt on the hinge is the darker color of the halftone. Also, if you look at the SP, the screen half looks like it can be 2 colors its self, with 2 different parts. Also, notice that the Nintendo logo on the back of the screen face is a unique color as well. Red (or grey) anyone?
