Hi, i read something about light turning red due leaving gravitational fields. A long time ago i played a game called ascendancy which was about colonizing solarsystems and battling other species and they had a few different kinds of stars in it, a few of these where white and blue dwarfs and red giants. First of all, is that right in real life? And if so, is the reason for the colors the composition of gasses of the sun or the gravitational field? n00b so don't be rough on me , please do correct me whenever i said something stupid .
