Review color and theme choices

However, I am color blind and there is not enough contrast between the
color for the URL links and whatever color the background is.  The
unhilighted URL links blend into the background to become nearly
invisible.  1/5 males are color blind, usually to greens.

My advice is Black background & White text.  Mobile PC users need to save
battery power via Black background.  White background causes snow
blindness.  Yellow and Black produce the highest contrast.  So Yellow URL's
might be a good choice, plus they look like sticky notes of interest which
is what they are really.

I'm not sure that we can go for black/white in the default, but we should certainly fix the color schema so it's more accessible.

An alternative might be the ability to select a "night mode" theme dropdown that has higher contrast.

Hopefully sorted!
