I also voted black as we in Canada are not allowed a grey or a brown or a mismarked Landseer in the show ring.(not that I show,cause I don't)However I think most when Newfoundland dogs are mentioned would think black right away.I guess it is like the classic little black dress that goes with everything.
After much thought, I had to vote black. But, it was a weak vote. As my neighbor says, "Morgan (black) is very pretty, but that Quark (landseer) is one sharp-lookin' fellow."
