Not sure if you've looked into it yet but I'm pretty sure Rolls-Royces have like 15 or 20 base colours metallic and otherwise and then a zillion hues that they'll add in to specifications... not sure if you could get a paint code for your specific desire but with that many combos it would probably just be a question of whether or not you can get a code for a white or light silver you like and blue flake/hue.
