title: Change settings on all Windows Forms forms
body: <p>I have changed my <code>app.config</code> file to allow the user to change the color scheme of the program. I can figure out how to change the background color of the form they are on where they change these settings:</p>
  
  <pre><code>Color colBackColor = Properties.Settings.Default.basicBackground;
  this.BackColor = colBackColor;
  </code></pre>
  
  <p>But how can I change all of my forms background color? It's like I still want to pass all my forms to a function. I already asked that question and someone told me to use the <code>app.config</code> file. Now that I have done that, am I using it wrong?</p>
