BLACK, BLUE etc. (declarations) should be recognised as definitions and
not other symbols.

The relevant java snippet is as follows:

/**
 *  <i>Standard draw</i>. This class provides a basic capability for
 *  creating drawings with your programs. It uses a simple graphics model that
 *  allows you to create drawings consisting of points, lines, and curves
 *  in a window on your computer and to save the drawings to a file.
