I've just started playing this game and notice that curiously, when you first start a game the background of deep space (zooming out) is black.  But later when I load a saved game, the entire space background will be this blue or sometimes red-orange color, very vibrant and neat but I actually prefer that more black color of space at the farther zoom levels.  I can't figure out if this is some kind of technical glitch or just a game feature, and I can't understand the pattern of when it's supposed to be changing color like this.  Anyone know?
