Detailed Description

Color property of a (UGroup or UBox) container.

this property specifies the foreground color of a container. It is inherited by children, except if they have their own UColor property, or if their UStyle specifies that they don't inherit UColor.

As for other properties, a UColor object should be added to the attribute list of containers. It can also be inserted in the child list in which case it takes effect on the following children.
