Well, my original reason for the amber glow in those scenes was because of restoring that first deleted scene. In it Palpatine comments that "the hour is late." At first, I figured that the following scenes occured later in that same day, and thus, would require more of a late-in-the-day coloring. With Padmé changing her clothes in practically every scene, it's hard to figure these things out. Have to track down the script, see if it says anything telling. In short, I just want some of the images to POP out more. Give them more life against all the fabricated CGI backgrounds.
Now that I am becoming more familiar with manipulating specific colors in a shot, I may do more to balance out a lot of that Geonosis orange color scheme. The challenge is finding something pleasing enough to the eye because you can't watch some neon green tinted planet for 20 minutes (I had enough qualms about it in a 3 minute fight scene in my own movie).
Last night, I also took out much of the blue in the analysis droid and Dex diner scenes. My lord does George love the color blue! Beyond just the fact that draining it out creates a more OT look, I feel the blue softens up the imagery too much.
