title: Designing an Etched Border
body: <p>I want to design a GUI with theme of Black, but my etched border looks raised etched type.
  I want to make it look lowered etched type. I can't find the color combination to do that. How would I do that?
  It's looking like this, but the difference is that the background is Black.  </p>
