Android - Collection.shuffle返回变量

Question

在我的新应用中，我需要从列表中随机播放颜色，然后将其分配给变量。变量返回什么？我认为变量会返回颜色，例如colorone == Color.RED，但是当我打印它们时，它们会返回值-256，-65536，-16776961和-16711936，有没有办法让它们返回颜色？

public class MainActivity extends Activity
{                   
       public int colorone;
       public int colortwo;
       public int colorthree;
       public int colorfour;

       @Override
       protected void onCreate(Bundle savedInstanceState){   
                 super.onCreate(savedInstanceState);                       
                 setContentView(R.layout.activity_game);    

                 shuffle();                              
       }

            private void shuffle() {
                // TODO Auto-generated method stub
                 List<Integer> numbers = Arrays.asList(Color.RED, Color.BLUE, Color.GREEN, Color.YELLOW);
                 Collections.shuffle(numbers);


                 colorone = numbers.get(0);                      
                 colortwo = numbers.get(1);
                 colorthree = numbers.get(2);
                 colorfour = numbers.get(3);


             }
}
