personal opinion here: if you go gold, then it'll look like brembos (which they aren't) so to some people you'll look like a fake. yellow, is very eye catching, but to me yellow + red doesn't work. I'd go a darker colour. Safe would be satin black, but that may be a bit boring for you. Other suggestions would be a dark bronze, or a gunmetal grey, if you wanted to go really out of the box, go and find some midnight purple!
