These Trouser suspenders change color from white to red or vice versa in a flash. It is even possible to make the color change in rotation; if the left hand suspender is red; the right hand one can be white, they can switch back and forth! The preparation time for this trick lies in the action of the effect itself. Each color change is the set-up for the next color change. This trick may be performed as many times as you want back to back!
