Actually it's true: the pornographic term "blue movie" does have something to do w/ color....or actually, the lack of it. Pornography in it's earliest days was very hard to make, film producers had to be very clandestine with their undeveloped product and budgets were nearly non-existant.
So quick, cheap ways to develop black and white film often produced a movie with a bluish color tint to the film. Often shown late at night in stodgy seedy movie houses, **** audiences viewed the cheap bluish films....and coined the name "blue movie" to cheap **** films.

- This answer has given the historical backgroud of the coining the name. It is more realistic and far from funny ideas and kiddings. So I choose this as a very good answer to my question.
