so i've been wondering recently, sometimes I see gels that are two colors, like a primary red and a primary green on a par, ,half of each. Now, I know that they are just normal gels, cut in half and taped together. I also konw that people say to use gel tape, and i have heard references to gelt ape sevearl places. But, a google search never turns up anything! Neither are there aything on rosco, gam websites, or retail places like sld lighting. Where can I get gel tape from? I am interested in useing two different gels together! I could just place them both in the frame, but i want to make sure they stay together well and don't slip apart leaving a white crack in the middle thanks!
