I found Milla's question regarding the Agent's skin coloring interesting and amusing. So it gave me the idea to experiment and change a graphic in GF2.
In so doing, (understand I'm not talking all graphics for the Agent, that would be a major undertaking) I was able to change my Agent, just on the inventory screen, to a long haired blonde w/blue eyes and red lips, black outfit w/silver-grey tights, black boots and a rather enhanced upper torso (in good taste). By making just these changes and using Jeff's original color, the skin tone lightened significantly.
FYI, I used resedit on a copy of the GF2 graphics file to do this.
