I actually like the way it is now, but I'm sure I would also like it in black or silver. Silver is pretty much the OEM color so I'd probably go with black if you are going through with a re-paint.
Maybe sleep on it for a couple weeks? I've made mods that gave me some mod remorse immediately after, but then after a while that feeling went away and I like them just fine. Looking at your ride, I don't think you need to change anything. The body color with the custom painted wheels and calipers is unique, personalized and looks good.
