What if Virgil was the orange side?
- He was the first "Dark Side" to become a light side, and has an ominous past we yet to know.
- He was the only side to be without a colour. Maybe he was Orange, and left that colour behind when he left the Dark Sides, only to gain the purple when he was accepted into the Lights.
- This could come hand-in-hand with the Paranoia theory; the Virgil-was-Paranoia is a widely known headcanon/theory. We know Anxiety was monochromatic w/ grey but became purple (unless you read into the Bravery theory, in which Virgil becomes Bravery, anxiety being a side gig -- kind of like Morality with emotions). Perhaps Paranoia's colour scheme was orange.
