Randy, the website I have from the UK showing paint codes does not show a Colorado Yellow paint number code only a picture example of the color bike.

I did a little digging and think maybe the code is 002. Yet pictures of that code in touch up paint seem more yellow than what I assume you have.

Best bet is to check on line at Glasurite or BASF, or a local auto paint shop for their color samples starting with 002 and see if anything comes close.  Good luck and hunting. St.
