Here’s my attempt at changing the tint of Exegol (from blue to green) without changing the color of the lightning. I still have no idea how to handle the lightsabers, but this is a start.
Honestly, I was fine with the original blue hue. However, the contrast between the force lighting and the new green hue of the planet is pretty cool. Also it definitely reminds me of the clone wars arcs on Dathomir with the nightsisters and their force magic. Not sure if that was your intention, but a nice call back to the prequel era regardless.
Maybe someone could isolate the Nightsister magic sound effects from The Clone Wars and add it to some Exegol moments to convey the feeling that a mysterious power is at work.
