OK what-face says the face in question is gnus-summary-high-read-face but when
I put (modify-face 'gnus-summary-high-read-face "cyan" nil nil t) into
.gnus it says invalid face.

Debugger entered--Lisp error: (error "Invalid face" gnus-summary-high-read-face)
  internal-set-lisp-face-attribute(gnus-summary-high-read-face :foreground 
"cyan" 0)

Maybe it has to be in the context of gnus running?

The link above was broken. But I found this, not sure what it is telling
me.
