On the Subject of Quilting

Maybe you should quilt while you’re ahead...

• Press the sewing scissors to cycle through patches on a quilt. The quilt is one of the quilts depicted below, chosen randomly.
• All but one of the pieces will be colored, and the other piece will be white. Determine the real color of this piece, then press the round button corresponding to this color to disarm the module.
• The quilt follows four color theorem, and there are exactly five patches of each color. Not every patch other than the white one will be displayed, but the white patch’s color can still be determined.
