I see no one has responded to this post yet. So, at this point I would recommend contacting your local Xerox Support Department to speak with a Product Specialist for more assistance. Please call 1-800-821-2797 or 1-800-835-6100.
I've already tried the official route without success.
It has only been 3 workdays since I posted the question... I'm still hoping someone from the Xerox Design department will have the info, or a helpful private citizen with a WorkCentre will slap a color swatchbook on the blue and cream panels and read the color code for the plastic panels (it only takes a few seconds).
Not everyone reads the forum daily.
