Regarding the colors, I believe James will correct it, all the colors became lighter, some items took on a completely different color.

Seeing weird stuff with the wall tiles and transparency, too.  Some wall tiles will let you see through and some won't.  The east wall of the casino will alternate between transparent and solid as you walk along it.  Interesting thing is the window tiles are the solid ones.  Could be a cool feature if its only the window tiles that let you see inside the building.

The color gradient seems off with titles.  Guizinh0's deep red nihilist title, now, is the same color as my low level demonic title was before the patch.  Anything below pure/damned looks really washed out now.  The rest of the colors look great!  Gear detail is much more visible and the color blue really seems to pop now.
