I like it.From how I saw it, I figured the colors were based on the time of day.
Batman Begins- Dusk
The Dark Knight- Night
Batman 3- Dawn??
???what...
Hmm, I could see a greenish tint being used, especially if the villain is Riddler.
Other than that I don't know, I think the blueish color is perfect for Batman. Gray perhaps?
The way I've intreptated things, I figured they were using the color schemes/opening titles to represent different times of the day
Batman Begins- Dusk (orange, brown)
The Dark Knight- Night (blue, black)
Batman 3- Dawn??
So if I'm correct, I'd say they'd use brighter/warmer colors (yet keep the dark tones) to represent Dawn. Have it opposite of the way the colors were used in Begins to show that the Sun is coming up.
