The second new product, ColorMerge, is an attachment that adds full dichroic colour mixing to the ETC Source Four. Since the Source Four is pretty much the industry standard, you can see where High End's thinking is going. It attaches between the lamp house and the lens and doesn't interfere with the gate area so you can still use patterns, irises and gobo.
It uses the same borosilicate glass found in ColorCommand so delivers the same benefits of colour consistency. Expect to see production versions of both at PLASA.
