Playing around with the character's visual incandescence, and, since he is a harried 'everyman', duplicating him to get a feel for him being with a herd of other office workers, coming out of the elevator, heading towards yet another 8.5 hours of Dante's inferno, just hanging on until Friday afternoon.  I'm coming to the conclusion to discard the grey color for the screw-base, since I really don't think that it adds anything worthwhile.  This character's imagery is dependent on visual simplicity.  I think that there's room for a few visual clues/cliches, but not much, or it all starts to break down.
