For instance, see:
http://www.classicalnotes.net/classics3/appassionata.html

This renders for me with a bright white background and blue text. But
note that for me, anything which changes the background color of my
window breaks the way I use GNU/Emacs.

Let me motivate my above patch request/suggestion:

"Difficult" in this case is subjective and dependent on the way my eyes
work, or in my case
(http://en.wikipedia.org/wiki/Astigmatism_%28eye%29#Based_on_axis_of_the_principal_meridians),
the particular way my eyes don't work. I'm sure that a healthy person
can see the text, but for me the bright white background makes the text
effectively invisible (the background white "bleeds" into the letters).

In conclusion: I can't expect shr to select colors that work with my
eyes, and I don't know to say that there is any problem with how shr
selects colors. But I would like eww to allow me to say "I've set up
Emacs to work with my eyes, please don't touch the background and
foreground colors I've set up."
