+@subsubheading Answer

+Gnus' built-in simple HTML renderer (you use it if the value of
+@code{mm-text-html-renderer} 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
+@code{shr-color-visible-luminance-min}.
