Generic matchesSafely method when Overriding a BoundedMatcher

Hi, Is there is away where I can implement the matchesSafely method without the need of use an outer value to compere with. In the video Testing Spinner we were forced to compare with the outer givenColor. Thanks!

 final int givenColour = Color.GREEN;
// Arrange
        BoundedMatcher backgoundColourMatcher = new BoundedMatcher<View,LinearLayout>(LinearLayout.class) {
            @Override
            protected boolean matchesSafely(LinearLayout linearLayout) {
              int actualColour =  ((ColorDrawable)linearLayout.getBackground()).getColor();

//Here we are using a outer value
 return givenColour == actualColour;
            }

            @Override
            public void describeTo(Description description) {
//Here we are using a outer value               
 description.appendText("Background color should be equal: "+ givenColour);
            }
        };
        onView(withId(R.id.linearLayout)).check()
    }
