My .02:
Silver looks fine, depending on the colours of the display on the HU. My JVC is silver coloured, with blue, red, and green on the display. I find that the red and blue work very well because the deck is right under our HVAC controls which are red and blue... go figure!
Actually, I can't remember all the colours of our HVAC controls, cuz my car is in the shop. Nonetheless, I think I'm right... correct me if I'm wrong.
I know you don't want to change from pioneer cuz of your changer, but the JVC has a motorized/removeable face, triple preouts, two AUX ins, a nice EQ, and doesn't cost too much. It also has id3/filename display/cd text/yada yada yada. The jvc does not do WMA decoding. I've never missed it.
Hope it helps a bit.
