Coloradjust.RGB -- set/get color
Set or get the adjusted color. If you set up a notification on this
attribute, you will be notified whenever the color changes. From
the Hollywood script the color is specified as a simple numerical
value containing 8 bits for each component. When you specify the
color in the XML file, it has to be passed as a 6 character string
prefixed by the #-character (just like in HTML).
