B6 S4 alloy wheel colour

[ARSEY4]

Morning all. I am trying to establish the colour of my b7 rs4 alloys as you cannot get paint from dealers. One of the s4 people has kindly found out that a b6 s4 has avus silver wheels code z17. What I now need to know is if the s4s are the same colour as the rs4 (b7).
Does anyone know?
Thanks
