Bringing this from Hal’s TROS: Ascendant thread, what do you guys think of making Palpatine’s Force lightning red? Here’s a concept from Skywalker Arts:

And here’s a quick video mockup from sade1212:

Personally, I don’t know if I’d use a full version in my own edit yet but I’d love to see it- there was a decent amount of support from others as well.

There was some discourse about it regarding confusion, but I don’t see it as something that needs to be directly explained. We see Palpatine absorb the power of the dyad and then he steps down in new (red) robes with glowing eyes again, so I feel like it’s safe to say the audience would understand:

Dyad power-charged Palpatine = Greater power than ever before = Red Force lightning color

The red could just be interpreted by the general audience as maximum Dark side power since red usually means Sith, and TCW fans would appreciate the connection to the Son in the Mortis arc.
