I have Sony DXC D-30 cameras and have been having trouble with certain gel colors not working well with the cameras. certain colors represent inaccurate and bleed all over the place. It seems that deep blue and purple are especially tough. I think I am simply using colors outside of what the camera is capable of dealing with. What I don't know is, is there any chart graph, rule, or anything to help me make Gel selections based on fact, not intuition.
