I e-mailed you directly on the site links and some information on colors.
As far as 3DHome's color, I thought it had a pretty fair range that you could choose from in 3D mode. I think you just clicked on the item (in your case, the door) with the color wand, and then choose the color you wanted. Unfortunately, although 3DHome drawings will convert up to chief, the reverse is not true, hence I no longer use 3DHome. . Let me know if I can help further - TomR
