      This executable extension requires parameters to be explicitly declared via the second method described in the IExecutableExtension documentation. This class expects that there will be two parameters, color1 and color2, that describe the two colors to be blended. These values may either be RGB triples or SWT constants.
      Specified by:
      setInitializationData in interface IExecutableExtension
      config - the configuration element used to trigger this execution. It can be queried by the executable extension for specific configuration properties
      propertyName - the name of an attribute of the configuration element used on the createExecutableExtension(String) call. This argument can be used in the cases where a single configuration element is used to define multiple executable extensions.
      data - adapter data in the form of a String, a Hashtable, or null.
      CoreException - never thrown but API
