Here is some help to explain the colors of a Pomeranian dog:
Chocolates will have coats that range from light to dark brown; a true chocolate Pomeranian will have chocolate skin pigmentation (nose, eye rims, lips & paw pads)
Beaver: This is a diluted chocolate and as such, is self-coloring. The beaver Pom will have beaver skin (nose, eye rims, lips & paw pads)
A soft, off-white. Creams will always have black noses.
Black tipped hairs; any base coat can have sable on it, i.e. orange sable, cream sable, etc.
A deep, intense orange.
Brindle: Technically this is a pattern. This Pomeranian will have a striping effect on the fur.
A blue Pomeranian is a diluted black color, there is blue skin pigmentation as well (nose, eye rims, lips, paw pads) A true blue will not have a full black nose.
A coat of two colors; each covering more than would be seen with a simple marking.
