Don't forget if you use paint you must soak all emblems to be painted in bleach for 3 days...replacing the bleach and wiping down the emblems every few hours seems to work best for me.
I don't think I'd recommend JUST using plastic paint (Krylon Fusion) without bleaching. I did that on my headlights and it works great but the emblems will be more exposed to the elements and I'd be weary of it lasting long. Prime them with a plastic primer or adhesive prior to painting. For a gloss look you can just use a can of Rustoleum Automotive Clear. This is how to properly go the painting route. Most like to change it up so they use plasti-dip...I like things permanent

PS Plasti-dip would be good if you are unsure of the color scheme at first. Once you are sure you can always go permanent with paint. And to be honest, don't be afraid to color match your emblems if you are feeling that scheme. One of the nicest cars I've ever seen is owned by Tastic and he went color matched...looks sexy!
