Make Luke’s ghost in TROS green to “honor” the Irishness of Ach-To.
WAIT WAIT HEAR ME OUT!
We only see… what? four force ghosts throughout the whole Saga? Why not have each force ghost glow a different color?
Obi-Wan could be white
Yoda could be green
Anakin could be blue
Luke could be teal?
Or, since kyber crystals get their color from the user through the force, what if all the ghosts matched the color of the ghost’s lightsaber? Luke and Yoda could be green, Anakin and Obi-Wan could be blue, Leia could be purple. Perhaps we should move this to another thread.
