I think I see the problem: it is somehow related to bug #19802.  In
particular, even if I do this:

  M-: (set-frame-parameter (selected-frame) 'background-color "black") RET

I still get nil from (frame-parameter nil 'background-color).  And
shr-color-check relies on the latter to report the background color of
the frame.

So I guess solving that bug will also solve this, or at least move
closer to its solution.

Richard, can you confirm that you see on your system the same problem
with 'background-color' frame parameter on a TTY as described above,
i.e. that setting that parameter in frame's parameter alist doesn't
cause frame-parameter to return the value?
