Head spot like a yellowbelly, some flames but not many, speckling in the aliens like a yellowbelly, similar color to many yellowbellys.
The belly reminds me of a cross between a normal and a yellowbelly, there's some speckling in the belly and some dark black down the sides of the belly too along with a yellow tint that many yellowbelly's have
Most if not all specters have a lot of striping and keyholes in the back stripe.
