Here's an example of a Land Cruiser in silver/silver and silver/black. I think silver and dark gray works for the color match (especially in front bumpers), but colors not so much. Of course, It's all subjective. In the above pics, I think the silver looks better. Maybe just because it's different as we are mostly used to seeing black aftermarket bumpers.

I'm trying to picture the Victory bumper on the 4R in silver and not able to visualize if it would look good or not. Definitely not looking for a mall crawler look, in fact just the opposite. The black victory bumper in the earlier post looked pretty good, so I'm leaning towards that.

The only example I've seen on a silver 4R is the Lifestyle Overland rig, which I thought did look pretty good. Thanks everyone for all your comments!
