I'm looking to build a "twilight" world, where days are like twilight even when the sky is clear and nights are...very dark. Cloud cover might be able to turn day to an early night. I do envision a day/night cycle and capability of supporting advanced life. Ideally, I'd like the planet to have seasons, though I don't care if it overall skews colder or warmer than earth.
So far, my research for how to achieve such a world would be to have a planet orbiting a red dwarf star. Or rather, a moon orbiting a planet orbiting a red dwarf star since I'm trying to avoid tidal locking. Gas giants are suggested, but I fear they may be too bright.
I have a basic idea of what I need (axial tilt, rotations, etc), but I'm lost in the hard planetary astronomy, such as how a gas giant might affect the brightness of the sky or might help heat a dimmmer world, or even how to keep the sky largely dark. Or if I'm barking up the wrong tree altogether.
Side note: Yes I am assuming the planet can withstand the solar flares.
