Gestalt Selector for the Color Picker
To test for the availability and version of the Color Picker Manager, use the Gestalt function with the selector defined by the following enumerator:
enum {
   gestaltColorPickerVersion   = 'cpkr' /* returns version of Color 
                                 Picker Manager */
}; 
If the Gestalt function returns a value of 00000200, version 2.0 of the Color Picker Manager is available. If the Gestalt function returns a value of 00000100, version 1.0 (that is, the original Color Picker Package) is available.
