Luminous is a recessive, ultra rare marking that allows a dracovix to display bioluminescence on its body, the ability to glow at will. Luminous can affect one marking by lighting it up entirely, or by filling it with small spots or stripes, or Luminous can present separately as small spots and stripes around the body. Luminous spots may not exceed a certain size, and as small stripes, Luminous stripes may not cross over and connect with each other into Y's, X's, and O's. The markings that Luminous can light up completely are: Dun, Freckling, Dapple, Spots, Streamline, Stripes, Python, Cobblestone, Marble, Border, Rings, Emblem, and Hallowed. Dracovix with this marking are capable of turning on and off their lights at will, and may be depicted in art without this marking showing even if they have it.

On its own, Luminous must have a hard edge.

Luminous may be any color at all that can produce light. Luminous must be a bright color, and cannot be gray, brown, black, or other dark colors.

Luminous may present over all other markings, including white markings. When Luminous is illuminating another marking, it can allow a marking that would otherwise be hidden by the markings below it, such as white markings, to appear on top, but only when glowing.

Additionally, Luminous can cause a glow coming from the back of the dracovix's mouth, and may additionally light up all free areas such as the flesh, claws, horns, and mutations regardless of whether the main part of the marking is modifying another marking or not.

If a free area is glowing with Luminous, you don't necessarily need to have Luminous present elsewhere on the body.
