Hello, I don't know where is my wrong, but I need a help..

I need to do SaveInstanceState to save the Background color of editText, but if I do rotation, the color is not save.. someone can please help me with that?

this is my code:

public class MainActivity extends AppCompatActivity { private static final String KEY_COLOR = "KEY_COLOR" ; private Button mButton; private EditText mEditText; private boolean mlsBlue;

@Override
protected void onSaveInstanceState(Bundle outState) {
    outState.putBoolean(KEY_COLOR, mlsBlue);
    super.onSaveInstanceState(outState);
}

@Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
    super.onRestoreInstanceState(savedInstanceState);
}

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

    mButton = (Button) findViewById(R.id.button);
    mEditText = (EditText) findViewById(R.id.editText);


    mButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
