I have a 2004 Toyota camry LE V6. the car is white and I replaced the grill and the headlights with black. I was wondering if the trunk emblems are removable so that I can take them off and paint them black and then reinstall them. Does anybody know if this is possible without messing them up.

 

You should be able to do this, just take your time.
I would look from the inside of the trunk out to see if the emblems are held in place by pins or are adhered on with glue/tape.
If pins, try to push them through from the inside so as not to snap the emblem.
Painting them black should be as easy as a little sanding of the finish and applying the paint.
Just take your time. Look on eBay for emblems for your specific Camry model to try and see if there are pins on the emblem that go into the trunk or are just adhered via adhesive.
