title: Setting Custom Color for Title Bar
body: <p>Ive been learning to build a GUI in Python recently and have had trouble figuring out one key feature I am looking for on my GUI: To colorize the titlebar.</p>
  
  <p>Im mostly working in QtDesigner stylesheets but have no issue typing out code in the .py if I need to.</p>
  
  <p>Ive had issues finding relevant examples in PySide2 as opposed to PyQt5, I prefer to use the Qt Team official modules(PySide2) if possible. If anyone can point me in the right direction it would be appreciated greatly.</p>
