Body colour or strong contrast will always work 
If it has to be gold, then a satin bronze or copper perhaps 
The silver trim as has the rest on mine has seen much better days and was thinking about this myself.
Problem is, my cars prestige blue so can't decide if it will be too much 
When I rebuilt all the brakes / suspension a couple of years ago now, I did paint the brake callipers in the same colour which worked out very well imho
The Turbo Weasel also had 'OPC' calipers, and worked fine, becaise, after all, a layer of brake dust will obscure them if they do appear to garish. In my humble, Steve, for yours you could/should try the smoke grey like I did, or maybe some of the vinyl wraps as above. Blue in a blue car tends to, for me, move into 'chavtastic'. On smaller stuff, eg a Focus RS or soemthing it seems to fit fine, but for larger more 'luxury' barges like Omegas, it just looks wrong. Try googling images of interior of Mercedes, Audis, Jag even Bentley etc for inspiration for how they treat wood/leather/silver/chrome/graphite etc trim and its relationship with the 'base' interior colour.
In the Turbo Weasel cream interior, with wood, and graphite grey with 'piano black' accents worked rather well, I always thought.
