paint codes for 1975 SS

I am rebuilding my 1975 750SS from the wreck it has been since i got it in 1980 in Italy. I need to know the colour codes for the silver and blue paint and what type of paint to use on the head stock and fork legs to give that dimpled black look. I have not decided what to do about the ignition system yet as it has the original rubbish red boxes and magnito, any ideas.
