Paint code for silvery 20" Trident rims - Maserati GTS 2009

[rgl]

Does anybody know the paint code for silvery 20" Trident rims ?
The stock code is 94082319 says my Belgian Maserati dealer.
Trident 20" rims are factory made in 2 colours only :
"Grigio Mercury" with PPG paint code 226679
and
"Grigio"-full stop or "alusilver"

Thanks for any valid information
