This is an image from when Palp has red lightning. Question is, should the Saber reflection be purple, and should the force ghosts still be blue or would the redness of their sky drown out the colour?
I would say the reflection should be a mix of red and purple. As for the ghosts, I guess that depends on how you think the light works on Force Ghosts… I would say they should be grayish because that’s what a translucent blue object would probably look like under a red sky, but the Force Ghosts in the original seem to be light sources of their own, so they should be blue, but that might look unnatural… so maybe a pale blue?
