      A DESCRIPTION OF THE PROBLEM :
      In a textfield, under certain circumstances i like to change the background color to GREEN. And when the circumstances are not true anymore, I would like to restore the color back to what it was at the beginning ( ie default ).
      I can set the color to what looks like green. BUT i cannot restore the color back to the original background color. Its close, but does not match.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Run sample. hit green button. hit default button.

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      i expected the default background color to be set for textfield.
      ACTUAL -
      a close color is substituted.

      REPRODUCIBILITY :
      This bug can be reproduced always.
