title: Actual text color on disabled button
body: <p>VB2012: I am creating a button control and inheriting from the .NET button. Taking the base from here <a href="https://blogs.msdn.microsoft.com/jfoscoding/2005/11/10/building-a-splitbutton/" rel="nofollow">https://blogs.msdn.microsoft.com/jfoscoding/2005/11/10/building-a-splitbutton/</a>  Since I am repainting the button I have to introduce some code to change the button text when disabled.</p>
  
  <p>So from past experience I went right away with <code>SystemColors.GrayText</code>. But comparing that to a normal .NET button, the color when disabled seems a bit off. After experimenting the one that comes pretty close is <code>SystemColors.ControlDark</code>. I can't find this documented anywhere. Am I doing this poroperly?</p>
