SECR/LBSCR Paint matching?

*Mods, if this needs to be placed in different section, please do so, or let me know, I'll delete and re-post*

I'm planning t purchase several 3d printed locos from Gosport Rail Works. As it is either impossible or very difficult/expensive to get paints from the UK, anyone know of close matches to Wainwright Green, or Stroudley's Improved Engine Green in any of the generally available paint lines, such as Vallejo, Gamer's Workshop, etc..

Thanks

Jim
