Anyone know what type of finish to call these?

Hi,

I am in the process of trying to list a set of OEM H2 Crossbar Roof Rack from our 03 Hummer and I'm not sure what finish to call them.... Apparently there's two possibilities. These are silver with a black strip down the middle on the top of the crossbars and have black mounting bases. I know I probably sound like a goofball (lol), they were on my husbands Hummer.

Thanks!
