I'm currently working on a sign for one of my job's clients & in the description they say that they want the sign to be "Drees Green." I call my boss to ask if that was a typo(for dress. I don't know how much sense that makes, but whatever.) Anyway, he assured me that this was it yada yada yada I figured I'd google it. Nothing. I know one of the meanings for drees is dreary, so, are they asking for a dreary green or what? They have a green on their site, but it's not very 'dreary.' Does this "Drees Green" exist?

Hey there, I have no %100 percent answer. But for randomness

http://en.wikipedia.org/wiki/Drees

But that is not a color, it's a location in Germany.

When I hear this I think High fashion. So a bright pastel green?

But for your sake, I'd ask again. I would hate to design something only to find I used the wrong color. Stupid Clients...

I agree with Deanapii - it would be best to just ask your client exactly what they mean. I've never heard of "Drees Green" before either.

why not send your client here and ask him to show you the exact one.
Honestly there is no substitute for client communication.
It makes them feel important. Dont be afraid to ask for clarification this make you appear more professional than less.
Greens one of those colors that you could loath when looking at the wrong shade than what you image.

You probably already solved this, but have you ever worked with Pantone colors? It might be a name for one of those types of ink.
