I had the same problem with about any HTML mail.  The background was
grey and the text was maybe a bit darker or lighter grey.  Possibly
that's caused by using a light-on-dark emacs theme.  I'm using tsdh-dark
which comes with emacs.

Anyway, I could improve the situation with

  (setq shr-color-visible-distance-min 10
        shr-color-visible-luminance-min 60)

but it seems those variables have gone in the meantime.  But still HTML
mails are readable, so it seems the problem has been fixed.
