stars have their natural color when bloom mode is off, but when turned on, all stars become pure white
I think its because they are using some single default texture for all stars, and making it thus appear to be white.
Anyways, if stars could be changed to have their own color to them in bloom mode, or at least make it much more noticeable, it'd be appreciated, because right now for those of us playing starmade with bloom mode, there is no fun in going to different-colored star systems, because all the stars appear the same for us.
blue w/o bloom {F459}
blue w bloom {F460}
red w/o bloom {F463}
red w bloom {F464}

Even without bloom they have a white core, maybe some tweaking with shaders will improve the color a bit. Changing priority to trivial since this barely affects players at all.
