Red as a Marking or Secondary Color
What is interesting, is that while red can be the main coat color on this breed, it can also be seen as marking or as one of the colors in a parti (two color) coat
. And this is even more rare as the solid red.
Any time that a Pom holds two colors and the 2nd one is less than 50% of the coat (and certainly if it is only 5 to 30%), that 2nd hue can be interpreted as part of a two-tone coat or as a marking. When it is seen on several areas of the body, it is often classified as a secondary color.
So, with this Pomeranian (right; below on mobile), we see an amazing coat of black with red markings. Notice how the 2nd color cannot be mistaken for orange (this red is dark) and it cannot be mistaken for tan (the red sheen is undeniable).
There is always the expectation that a Pom will have a color change as he matures, but this black and red adult proves that red may indeed remain.
