I mean the colours make usability more difficult, as it lacks contrast. Ok, so its not all white, but a lot of very light grey, it's so bright I'm having to squint at my screen :)

Also, behind the File, Edit menu text etc on some programs (photoshop, notepad2) they are a bright pink colour (something to do with transparency?)

Now, I don't know about you, but after looking at that above pic for 5 seconds my eyes start to strain... too *bright* !

I tried to fiddle with it and it ended up just looking crap =\
