Since migrating to Creo 3 from Creo 2, I've noticed that the colors in my appearance palette don't look at all like they do in Creo 2. Same graphics card, same driver, same appearance.dmt file, same config.pro... same everything.
I've dug thru the config.pro file to try to see if there was a new color or graphics setting, but I've not been able to find anything. Then I tried updating my graphics driver - to no avail.
Any ideas as to why I can no longer see my nice, realistic colors in Creo 3?
Creo 2 palette looks like this...
Creo 3 palette looks like this...

Actually, in Creo 3 PTC changed the way the highlight parameter is calculated for realtime rendering.
In real-time rendering mode, highlight does not use the highlight slider. it is now tied to the reflection parameter. So appearances from Creo 2.0 that had no reflection, but a strong highlight will show up in Creo 3.0 with no highlight at all, due to a lack of "reflectivity" So there is no way in Creo 3 to have an appearance that has a strong highlight without also having a reflection.
In standard shaded mode the appearance looks mostly the same as it did in Creo 2.0.
There are some great new aspects to real-time shading in Creo 3.0 that are really great. however, there are a number of problems that make visualizing surfaces much worse than it was in 2.0. I really want the artificial non-reflective highlights back! highlights without a reflection or with super subtle reflection. YES PLEASE! 
Please review my post about the broken behavior of realtime appearances in Creo 3.
