Default part colour in SW2012 and other questions

Having just updated SW2011 to SW2012 I now find that the default part colour has changed from the normal grey to a purplish colour? Should this of happened or is purple the new fashion colour for 2012? Should I change back to the original colour by editing the default part template?

My second question (which I know must have been asked a 100 times before..) is that when I bring in new assembles from 2011 to 2012 many of the bolts and screws are not the original size but several sizes up. Is there an easy way to correct this?

Thanks in advance for any help.
