Currently they are bound to star type, so blue star blue background. Makes no real sense, but it feels right. So that what we decided to go with. We want to change the appearance for systems in a nebula as well. I think this might be added in the future.
Nice work. Sci-fi actual space games tend to have indeed boring skyboxes. The issue is also that real space is pretty dark, and that NASA space pics are amplified or fake colored, so everyone expects unrealistic fantasy art. I find the 1.2 sky, though, too sharp, as if ... it would need to be more milky and smooth? Not sure.
Any chance to get access to the shader files? If it is just shader coding, of course. I'm not that bad at these things...
- Here's rather a star dust implementation:

- This is also some nice particle work:

- Also a rather soft space screen:

- This nebula generator is also interesting:
Here are some composition ideas
- The background, not the planet or the front assets:

I would also parallax move the background a bit with the mouse cursor, in order to show a tiny bit of depth. In general, I would go straight 3D and play with different levels
I think that the space background should be always more artsy than technical or realistic. Because space itself is dull, empty, and boring. And in games like Stellaris, I still have constantly to look at that background. It is also interesting how Master of Orion (not that I'm playing anything else than Stellaris, of course!) solves this topic. Interesting issue though. Look forward to more.
