Does shr-color-visible-luminance-min have any effect on a TTY?  I
think Richard is using text-mode frames that support only 8 colors.

So perhaps try this in a TTY frame, and see if you still see no
problems.  If you do, perhaps we need some more magic in shr-color.el,
or maybe even in tty-colors.el (unlikely).
