Border is a rare marking modifier that adds an outline around another marking. The markings that Border can modify are any markings that do not have only a gradient edge. Border can modify up to 2 markings. In dominant form, you can have Border modify as many markings as you would like. If there are no markings for Border to modify, then Border will create a line either right down the mid line of the dracovix starting from their throat and ending at their tail, or down the dorsal line starting from the back of their head and ending at their tail tip, acting the same as Streamline if it were located on the belly or the spine.

If both Border and Bi-Color are present and the dracovix has no other visible markings than just those two, not including full color modifier markings like Axanthic, then either Bi-Color can modify Border as a standalone marking, or Border can modify Bi-Color as a standalone marking.
