Reducing blowout by 2/3rds of the spectrum (or more) seems like a good thing. I don't get the "myth" people. Maybe they just prefer blue or green dim lights? Historically it's got some influence from black and white photography, where black and white film was typically least sensitive to the red spectrum and sometimes not sensitive at all, giving a small frequency window where one could operate in a "dark" room without exposing the film the photographer was working with, because the human sensitivity to red is many times better than the film's sensitivity to red.
