The new color scheme gives me a cold, techie feel. I like it.
Laslon was talking about the "radar" on the Tactical screen. Maybe having a colour (same or different) beneath the Power Wheel could be a good idea? I don't really know.
But, as was said for the Tactical screen and it's new colour scheme, the green-red health pallete was intuitive. We'll see if this one is as well. We could also claim that if it's not red, it's good, or something along those lines.
