Colour code for old ocean 30?

[Falcoron]

Hi,
just wondering is there colour codes for old ocean 30 ( broom) boats? I am repainting her and the upper deck gel coat is white but with a very slight greenish tint, looks for all the world white until you put something white against it.

I don't have anything I can remove from the boat to get the colour scanned, but I'm sure its probably one of the BS standards.
Anyone know or know where I could find out please.
Thanks

I'm sure the UV will have affected the colour over the years but how about borrowing a Pantone book from someone and matching the colour from that?

Would be easier to match it with some pigments, it would have changed by now.
