I want to highlight the border of a sprite .

I want to highlight a border of a sprite. I have a sprite type variable "m_sprImage" in which I want to highlight border.

I used below codes but not highlighting as per my game requirement.

  TintTo* action = TintTo::create(0.1f, 255, 0, 0);
   TintTo* actionReverse = TintTo::create(5.5f, oldColor.r, oldColor.g,oldColor.b);;
   TintTo* actionReverse = TintTo::create(10.0f, 255, 255, 255);;
   m_sprImage->runAction(Sequence::create(action, actionReverse, NULL));
   m_sprImage->setOpacity(255);
