long overrideDefaultColor(int colorSysEnum, double v1, double v2, double v3, double v4)
This method sets the default color help by the API object to that defined by the given arguments (See Color Specifications).
The initial default color is NULL and, if this is the case when a feature is created, the featureís color is determined by the given feature code through the mapís color index file. This default behavior may be restored (after a color override) to NULL, by calling this method with colorSysEnum = 0. (When the method is called with colorSysEnum = 0, the other arguments are ignored.)
