The gold hubbed ones are the Skyway Graphites, expensive as fook, and there's more than one type, the more squared off ones are Campagnolo hubbed ones and are even more expensive. You could annodise the normal alloy ones but you'll have to break the 5 long "rivets" that hold them all together, then you'll have to get some more made up or use long bolts and nuts when you reasemble, which dont look too good.
Another way is to use glass paint on the alloy which will give you a similar effect but not as good as getting them annodised... someone on here did that or something similar, must have been over a year ago so use the search facility and see if you can find the post with the pics.
