Siamese is a recessive, uncommon marking that turns the entire dracovix to a leucistic-like off-white except for its extremities, the face, the wings minus the shoulders, all four legs, and tail.

Dracovix who have the visible Siamese gene may have red pupils. The red hue can be subtle or bright, and can be outlined by the usual black or dark pupil color. This trait is not inheritable to offspring who do not inherit the Siamese gene.
