When I started to paint my very first Space Marine I got from Christmas a long time ago (2nd edition), the only paint I had was red at the moment, because the SM on the box were red, so I thought I HAD to paint them red.
Later on I discovered they were many more chapters and colors, but never stopped painting my marines red.
Red is cool.
But, I don't play, I'm more of a painter, so don't really know how to play BAs. Yeah, you can denounce me to the Inquisition.
