title: C# Trackbar custom colors
body: <p>this might be a very global question but here we go:</p>
  
  <p>I was wondering how I could make a trackbar like Virtualbox.
  They have a trackbar that have custom colors at the bottom to show if you've assigned too much  RAM to your virtual system.<br>
  Now my question is: How can I give my trackbar custom colors?<br>
  I have read something about e.graphics etc. and overriding other functions, but I can't seem to find any information about this ):.</p>
  
  <p>If you know what I mean and have sources to good tutorials and/or examples that would be awesome! Because I really don't know where to look anymore :(.</p>
  
  <p>I am programming in C#, WinForms.</p>
