With the new multi light source LED fixtures coming out these days, there has been some attention paid to the multiple color shadows that they produce. Whether it is due to RGB LED clustering or separate LED chipsets, there can be a bit of color separation. From my days in lighting design, I rarely had issues with shadows of odd colors. There was a bit of separation between the cool and warm washes and occasionally an RGB issue if a dancer got too close to the cyc but it was never a big issue. As you are evaluating the numerous LED fixtures coming out keep in mind that color separation is a fairly minor issue when used with many fixtures of a stage wash. There are a lot of new lighting technologies that don’t follow the traditional lighting technologies we have become accustomed to.
