Someone posted this yesterday on a newf mailing list I am on, so I had it handy:
Recognized Newfoundland colors are black, brown, gray, and white and black.
Solid Colors - Blacks, Browns, and Grays may appear as solid colors or solid
colors with white at any, some, or all, of the following locations: chin,
chest, toes and tip of tail. Any amount of white found at these locations is
typical and is not penalized. Also typical are a tinge of bronze on a black or
gray coat and lighter furnishing on a brown or gray coat.
Landseer - White base coat with black markings. Typically, the head is solid
black, or black with site on the muzzle, with or without a blaze. There is a
separate black saddle and black on the rump extending onto a white tail.
Markings, on either Solid Colors or Landseers, might deviate considerably
from those described and should be penalized only to the extent of the deviation.
Clear white or white with minimal ticking is preferred.
Beauty of markings should be considered only when comparing dogs of otherwise
comparable quality and never at the expense of type, structure and soundness.
Disqualificati ons - Any colors or combinations of colors not specifically
described are disqualified.
