Here is some help to explain the colors of a Pomeranian dog:
A medium brown
A mix of white, grey, brown and black
A lowly saturated light to medium yellow. Creams will always have black noses.
Black tipped hairs; most commonly seen on a background color of silver, gold, grey or brown
Actually a reddish orange color Pomeranian
Brindle: Technically this is a pattern. This Pomeranian has a base color of gold, red or orange - with strong black cross stripes
A blue Pomeranian is a diluted black color, there is blue pigment on the nose and eyes. 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.
