That is interesting. His description was a good way to express it, as
I immediately recognized the old problem.

I have actually sort of promoted it into a color scheme: in some old
applications I wrote I did not know how to fix it, so I let the red on
black, when originally intended for white on black. But I got so used
to it, that even after I learned to fix it I left it unchanged. And in
some new applications I wrote, even in object graphics, I found myself
explicitly choosing (through triplets) red for lines to plot over
images.

If anybody is wondering: the "missing" plot lines in Postscript Karen
described are actually plotted, but in the same color as the
background, so they are not visible.
