I used Duplicolor Perfect Match "Intense Pearl Blue (PB3)" on my '63 Tiger with very good results. Not an exact match, but super close. You can't tell there is a color difference unless you are a couple of inches from the area painted. I ended up masking off all the decals and then over spraying the frame. Just did touch up on the forks. This is a rider, so I was not concerned about ruining the "value" of the bike. It looks much better now than it did with all the scratches and chips in the paint.
