You will need Buccaneer Bronze, Buccaneer green and Buccaneer white from what i can tell. this site apparently has it , but it is $20 per can. You can probsbly match pretty close with Johnson Sea Horse green, and other Johnson colors which you might get a little cheaper (more common) The site is http://effena-co-llc5.mybigcommerce.com/paint-gale/

Sorry about that huntleybill, I had looked at color swaths online and thought the Johnson Sea Horse green looked like it was (or almost) the same color. One of the other guys may have another place to get it, but my search of the internet wasn’t successful in finding anything. What I have done in the past is to take a sample of the color i want to my local auto supply. They can make an automotive quality paint to match any color you need. My little Buccaneer is original and hasn’t been out of the shed much during its life so colors should be fairly accurate, but I think the paint colors may have changed in either 57 or 58 so may not be the same color. But you are right, now that i look closer the johnson paint is different (a lot). I have placed the Johnson paint chart and my Buccaneer below to show difference.
