When importing a key image of my daughters the color looks like a perfect match on the small image window, however, because my subject's pants are denim (medium blue)colored (using a blue background) they change to black in color. Then when importing a background the denim pants take on the background color and texture. The balance of the image looks great---just the denim pant color shifts.
I'm a new user--wondering if I need a separate background light. Help?

The problem here is simply that you are photographing presumably blue (denim) items against a bluescreen. This will always result in drop-out of some of the foreground. The greenscreen and bluescreen compositing technique relies on contrast between the background and foreground, so if a foreground element has the same colour as the background it will cause complications.
We are looking into adding new features to future versions of PhotoKey that will help to ease these problems. However, it will always be advisable to avoid colour clashes such as this whenever possible.
In the meantime you might have some success by raising the 'level' slider in the Key section.
Hope this helps.
