Very nice Saturn Paul, looks great!
As for colour, make sure you have Saturation way up high in the ToUcam settings - I keep forgetting this one until I get a few colourless images, then I remember to push it high again.. Go almost all the way, I use 90-100% most times.
The program gary is referring to is called "wcctrl" or "wcctl", do a search and ye shall find!
