As a rabid Transformers fan (I have a box under my house with all my original Transformers still), I was so hyped on the Shattered Glass universe - it's pretty fun!
What I found most amusing though was the color schemes, like you mentioned. The now evil Autobots are distinctly darker while the Decepticons are brighter, almost happy colors.
Look at the icons too. The Autobot symbol is now purple, and the Decepticon one is Red. In the normal universe, it's reversed. Apparently Purple = Evil!
