While I was messing with the lighting property I notice the bloom property kinda act like ray marching cube behaviour and I decided to create 2 really bright object, but the black hole is just a big ring circle, and the giant star is from the atmosphere glare property. And some more adjusting the lighting property and lighting instances I got these result:
Both look good to be honest. I guess in terms of logic, blue would make more sense since light at the outer perspective is still bright and looks a bit better. But if the player would be in the inner perspective, light would get redshifted.
