Sage Green paint code help

Hello I joined the forum with the intention of asking one question and I have ended up reading quite alot of posts as they have interested me, :)
 
Im from the UK and I am very interested in spraying my car Sage green. The problem is Hummers are very rare here and I am really struggling to find the paint code?
 
I rang a few places and they say they have no listing for Sage green, :(
 
Can anyone help me please?
