Joe-
Sorry, I just got a chance to check in and saw your question.
The color of the Cordura is Moss. They say it's pretty close, so I'm going to give it a try.
As far as the canvas or dropcloths, it's not water proof or water resistant, and I can't find any that is in the right color. I'll post up once we get it and give it a try.
Take care,
Kirk
