title: Default RGB color code for activity backgrounds
body: <p>I am adding pictures to my Android project and the background color of those pictures are the darkest of the darkest color (RGB: 0, 0, 0) but I can see the background color of the images is different from the background color of the android activities.</p>
  
  <p>What is the default RGB color code for the activity backgrounds or is there a method to get it?</p>
  
  <p>(Yes, I know that I could change the background color of the activities to the desired color instead, but that would require that I change all my activities' background color)</p>
