title: Changing Facebook Messenger colors to custom ones
body: <p>Because MAUF app has been dead since July 2017, I was looking for another way of changing colors in facebook messenger to the ones I want. Found something here: <a href="http://wanna-be.pro/facebook_messenger_dialog_color/" rel="nofollow noreferrer">http://wanna-be.pro/facebook_messenger_dialog_color/</a> </p>
  
  <p>I succesfully intercepted XHR request, managed to change it a bit (color) and sent the modified version back to Facebook. Unfortunately, nothing happened.
  I tried playing with it a little bit more, and noticed it changes color only if the specified color is one of the 15 facebook offers us to change in a normal way.</p>
  
  <p>Is there any way to set a custom color now, or has the facebook changed it in a way it's not possible by any method now?</p>
