title: How can I change the color of the JFXHamburger
body: <p>I use the JFoenix Libary to develop a program with JavaFX.
  The default color of the JFXHamburger is black but I need white.
  I use the SceneBuilder to design the program but I can not find any property where I can change the color.</p>
  
  <p>Does anyone know how I can do this?</p>
  
  <p>TIA.</p>
