I figured out that to make this work you have to override the getDropDownView when setting up the ArrayAdapter in the main activity.

public class main extends Activity {  
     @Override 
     public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);   
        setContentView(R.layout.main);  

        PatchedSpinner pSpinner = (PatchedSpinner) findViewById(R.id.spinner2); 
        ArrayList testarray = new ArrayList();
        testarray.add("item0");
        testarray.add("item1");
        testarray.add("item2");
        testarray.add("item3");
        ArrayAdapter spinnerAdapter = new ArrayAdapter(this,android.R.layout.simple_spinner_dropdown_item, testarray) {

           @Override      
           public boolean isEnabled(int position) {
               return position != 1;                             
           }

           @Override                
           public boolean areAllItemsEnabled() {
               return false;
           }

           @Override
           public View getDropDownView(int position, View convertView, ViewGroup parent){
               View v = convertView;
               if (v == null) {
                   Context mContext = this.getContext();
                   LayoutInflater vi = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                   v = vi.inflate(R.layout.row, null);
               }

               TextView tv = (TextView) v.findViewById(R.id.spinnerTarget);
               tv.setText(testarray.get(position));

               switch (position) {
                   case 0:
                       tv.setTextColor(Color.RED);  
                       break; 
                   case 1:
                       tv.setTextColor(Color.BLUE);
                       break;
                   default:
                       tv.setTextColor(Color.BLACK);
                       break;
               }
               return v;  
           }              
        };

        pSpinner.setAdapter(spinnerAdapter); 
} 

The layout that is being inflated is a custom layout called row.xml. it is used to set the display for the dropdown view.
