I keep staring at the color altered Fett pic on page one. I LOVE the breaking dawn look of it all. I just tried to do it myself with the scene in FCP 5, but I can only do it with straight color correction. Which means Obi-Wan's saber core turns amber, and it affects the color of the jet pack rockets and the laser blasts. So, without doing a full re-rotoscope, I couldn't make it happen. I hope you have more dynamic results. Inspired idea.
