Submarine anti-fouling paint

[dwheels]

I have on order an AFV Club 1:350 Guppy II submarine. I was a crew member on one of these in the mid 60's, the USS Diodon. This is my first ship model. I mostly build 1:72 aircraft.

During my tour, we went through an overhaul at Hunter's Point in San Francisco. While most ships seem to have a dark red paint below the waterline, I distinctly recall that the Diodon was a light green color. Would anyone know what color I would use to simulate this?

Thank you for your help.
