So by my count 19 Dark Blue and 12 Sky Blue ratings among the 16 skills. Sounds about right to me. Interesting how heavily tilted towards the "mental" stats the higher ratings are!
I understand your point about Stay Back! but have a hard time imagining a DM overriding the player light source area with an environmental effect. I've always considered this a Sky Blue rating.
Okay, took a big first stab at all the powers. Comments, thoughts, things I missed?
Looks pretty good. I think I'm in broad agreement with your ratings.
I like your rating of Secrets of the City. I mean basically what you have is a Gold rating if your conflicts predominantly take place in settled locales versus wilderness locales. Conversely, if they're predominately in the wild, you're looking at Purple to Red. Finally, if its a pretty even split, you're probably talking about a Blue rating given the sheer potency for a level 2 Utility (or a single Feat).
