This is a great tool. If you don't want the mess of food coloring, there is a product available in many tackle shops and the big catalogues/stores too called Dip n Glo. Chartreuse, pink, blue, black, pumpkin, red are a few colors that are available. I always carry chartreuse with me on every trip. A fishing guide that I once hired on the Lower Potomac, Glenn Peacock, once had a saying that sticks with me to this day, "If it ain't chartreuse, it ain't no use." In many of the waters that I fish, chartreuse is a great color and the dye will work on all but the darkest of plastics. It's pretty bright on some colors too!
