Original Paint Colour Codes

Any one have handy the code numbers and brand name for the original factory paint colour schemes? years 62 to 75.
Looking especially for the correct colour code on a '62 Atlas grey/silver for the fuel tank. Thanks to All. teddy boy.

I had my original 1972 fiberglass side covers in signal red matched at a local paint shop. The result was a bit more orange than the covers, but this does seem to match other signal red machines. Painted a steel tank to replace the fiberglass.
