Lot of that arts look so good… what do you guys think the deal is with the floating ash that Kylo observes?

This might be a weird idea. I recall the Exogol scenes being pretty blue, or at least having a blue hazy tone. What if we regraded it to have a more neutral tone, or give it a monochromatic, almost black and grey look, to emphasize this Sith throne world as a world of literal darkness. And later when Rey/Kylo use their sabers, they’ll really stand out well against the blackness.
