I'd like to start an association called Scientists Against Green On a White Background. We'd have semiannual SAGOWB (pronounced Sag-o-wab) meetings at AAS each year. We'd apply for NASA and NSF funding to go around to various departments and teach people not to plot their data as green on a white background. We'd talk about how when you use green on a white background in the figures in your paper, the data become invisible when printed on a black-and-white printer. It would be a heck of a movement. No more would the colloquium speaker have to say, "And as you can see from this figu--uh, oh. Well, it doesn't really show up, but if you could see it, my data clearly show that..." To demonstrate the problem, look at the following figure and squint your eyes slightly to simulate a typical computer projector. As another test, click on it and print it out on a B&W printer. Hilarity will ensue!
