I've got black wheels, kalaminos and they were ordered that way. I think the choice depends a little on the 'look' that you are trying for. If you want more of a 'racer' look then go black. If you want more of a svelte, well healed look go alloy. Silver is lovely either way. I personally wouldn't buy new. I bought mine (XK/R) a year and a bit old and it had already depreciated 50%. Could have bought an older one and saved a few bucks. They are very well engineered, and mileage isn't really an option.
