I had a peek at this, and the sample faces come from here:

(define-widget 'color 'editable-field
  "Choose a color name (with sample)."
  :format "%{%t%}: %v (%{sample%})\n"
  :value-create 'widget-color-value-create
  :size (1+ (apply #'max 13 ; Longest RGB hex string.
                   (mapcar #'length (defined-colors))))
  :tag "Color"
  :value "black"
  :completions (defined-colors)
  :sample-face-get 'widget-color-sample-face-get

But of course, you can't have two samples in the :format, I think?
So...  you'd have to create...  er...  a sub widget?  OK, I give up.
