Once this was posted here at cliosport.net forum.
I got that and quote:
"I can only offer the original paint code ( as applied by Speedline ), unfortunately not an RAL or Pantone. This was Akzo 7E 81208. Please be very very careful though. Gold is notoriously difficult to exactly get the correct colour match, I know it sounds daft, but primer coat, spray technique, baking temperature, all these things affect the final colour appearance. Clearly, when they are made in Speedlines factory it is with a highly controlled environment and process hence the continuity of colour match across thousands of wheels. "
no RAL or Pantone... sh!t. Thats all mate.
