There are a few subtle traits that specters have and she has all of them. Unless she proves though, she is just a normal. Specters do look like a normal to the untrained eye. They have a long stripe extending from the head. A long stripe extending from tail tip up. Markings are thinner. Little to no blushing or flames. Dusting of lighter color on lower sides. Clean bellys. High contrast between the base color and the color of the markings. Burgundy head spot. Often hatch lighter in color and darken up a little with age.
I didn't really suspect anything until she produced that pastel look-a-like though. That's when I decided to give it a shot with a YB breeding.
