30 * ColourSchemeProperty binds names to hardwired colourschemes and tries to deal
31 * intelligently with mapping unknown names to user defined colourschemes (that
32 * exist or can be created from the string representation of the colourscheme
33 * name - either a hex RGB triplet or a named colour under java.awt.color ). The
34 * values of the colourscheme constants is important for callers of
35 * getColourName(int i), since it can be used to enumerate the set of built in
36 * colours. The FIRST_COLOUR and LAST_COLOUR symbols are provided for this.

72 * If none of these formats is matched, the string is converted to a colour
