The Name gallery allows a collection of objects to be associated with names and other objects. The name gallery lists all fonts, bitmaps, named colors and object names used in any drawing or animation. Information on the name gallery can be found within the program help along with the manual.
The file named 'Blue Car' available from the Example Xtreme drawings 2 category from within the clipart is an excellent example of using named colors within your drawing. The files within the Photo albums and collages category can be viewed for an example of naming objects.
