These trouser suspenders/braces change color from white to red or vice versa in a flash. It is even possible to make the color change in rotation: the left hand suspender is red; the right hand one white - suddenly the left hand one is white and the right hand one red. The preparation time for this trick lies in the action of the effect itself. The suspenders are genuine at the back - that is to say you determine whether the start or end color is red or white and you may turn your back to the audience! Note: The performer can only turn around and show ONE color at the back - either the start or end color, and not both colors.
