Does anybody know what paint code Cigarette uses for its red?

You need to be more spacific of what you are wanting, which red?. There has been NUMEROUS variations of paint jobs over the years and they use outside painters as well. Your best bet is to take the boat to a qualified body shop or paint supplier and have them scan the paint to "match" what is there.

If you are starting from scratch.... Look for the numbers that match closest to what you envision. I know the boats I move for Visual Imagination back to Cigarette, they send paint with me in-case there needs to be a touch up during rigging...
