+How can I ensure more contrast when viewing HTML mail?
+
address@hidden Answer
+
+Gnus' built-in simple HTML renderer (you use it if the value of
address@hidden is @code{shr}) uses the colors which are
+declared in the HTML mail.  However, it adjusts them in order to
+prevent situations like dark gray text on black background.  In case
+the results still have a too low contrast for you, increase the values
+of the variables @code{shr-color-visible-distance-min} and
address@hidden
