Cooper Green - colour codes

[LordGrover]

At the Growl I saw a rather nice cooper green precat that had been resprayed recently. As it's something I'm going to have to consider at some point I'm keen to get the right colour - the one I saw was similar but wasn't the same as my 'original' cooper green.
The body code on my car is P422~2382B
On the two stickies here we have:

TVR014  Cooper Green 2  P422-MFA3B
TVR047  Cooper Green
R2576  Cooper Green  P422-2382B  Honda / Rover
P168  COOPER GREEN  2382B  2K
P168  COOPER GREEN  2382B  AQUABASE
-       COOPER GREEN 2  MFA3B  2K
-  COOPER GREEN 2  MFA3B  AQUABASE
-  COOPER GREEN  TVR.*0040  DELTRON
-  COOPER GREEN  TVR.*0040  ENVIROBASE

Clearly, the third option is the favourite but how does one ensure it's the same and not some similar facsimile?

Ask potato muncher. Malcolm works for S&D and they have the build sheets for a lot of TVRs he might even be able to tell you the right code straight away.
