OK, I think my screen is closer to a reasonable calibration, at least as far as brightness goes.
I'm attaching a redone color and a B&W version. I doubt this will convince anyone who disliked it, but Tony and Sharon, I tried to take into account your suggestions, and I think it's substantially improved. Please let me know what you think (and in particular, if I overdid the changes).
Edit: sorry, forgot one adjustment to the B&W. Here's the correct version.
