have you added any lights to your scene ?  if you have you can click on the scene tab on the right of your work area and you can select the lights individually, then in your parameters scroll down to the bottom and you'll find a colour bar and intensity bar as well as the shadow settings.

and no worries about being new and not knowing cause well i only found this out about a month or two ago and i have been playin around in DAZ for a year and a half
