as far as I can guess, from having an emerald green carpet in my bedroom is that emerald green would be a very dark green almost bordering on a flat color as opposed to pearlescent or metallic. This looks like an extremely dark polo green to me, perhaps it's the emerald we all search for (apparently called Arcadia green by Nasioc. http://members.nasioc.com/UserPics/14949/MySVX.jpg

EDIT: Correction I found this car on another site where he lists the polo green code number. On the other hand most products that I find in emeral green resemble this shade http://image.lik-sang.com/images/170...merald-ltd.jpg
