I also painted my emblem red. Main reason I did this was so that I could test some paint to see if it was close to Rio Red, so I could paint my fender.
Here's some pics (click for full-sized images):



Shortly after I took these, the glue I was using ate through the red paint on my emblem. I scraped it all off and re-painted it. I'm going to try gluing it back on when it is fully cured this time.
I was going to leave it silver with the black mesh, but I ran out of silver paint. I painted it black instead, because I had a few cans lying around (keep it fast, keep it flat black...).
I'm planning on painting the main grill body-color later, but for mow.......
