I have a Ubuntu server (18.04) that rebuilds itself on a schedule. Every once in a while on a fresh install, all the console text color will be a different color. Usually it's white on black, but sometimes its blue, green, or red (and maybe others, I can't remember). There doesn't seem to be anything obvious to link it to (bad install, etc).
Is the color there for a reason? What determines what color the text will be?
