As long as we're on that subject for a moment, I'd like to comment that
I learned back in the mid '80s that there's no such thing as a green
star. The frequency range for green is so narrow, that even if a star's
peak output is inside it there's going to be enough from one side or the
other that we'd see it as either blue or yellow. This, BTW, was from a
friend with a degree in Astronomy, so I'd tend to believe him.
