Mine is pearl grey which looks similar, LA7U i think off the top of my head.
Best bet is to take it to a proper paint place, and they will match it for you..... will work out better, as there are slight variations on the colours (when i went with mine, they had a card with different shades on it and matched the correct shade to my paint, to mix it up).
Also the paint is usually bettter quality too, so much better all round!!!!
