1970 Center Cap Paint Color & Code?

[challengermaniac]

Are the 1970 Challenger Center Caps the same Argent Silver color as the wheels or a different color/paint code? 

Thanks, Charlie

the wheel is a flat silver
the center caps are a coarse grain paint that feels like sandpaper , it is the saem paint used on the Non R/T grilles & the tailpanel on the SE
