title: How do I color widgets in LambdaTerm?
body: <p>I was playing around with the examples <a href="https://github.com/ocaml-community/lambda-term/blob/master/examples/buttons.ml" rel="nofollow noreferrer"><code>buttons.ml</code></a>, <a href="https://github.com/ocaml-community/lambda-term/blob/master/examples/checkbuttons.ml" rel="nofollow noreferrer"><code>checkbuttons.ml</code></a>, and <a href="https://github.com/ocaml-community/lambda-term/blob/master/examples/radiobuttons.ml" rel="nofollow noreferrer"><code>radiobuttons.ml</code></a> in the <a href="https://github.com/ocaml-community/lambda-term/" rel="nofollow noreferrer">lambda-term</a> library, and I noticed that all of the "dynamic" examples (i.e. involving events, resizing the terminal, etc.) were in black and white, while all of the color examples were "static" (i.e. no events).</p>
  
  <p>Is there any way to have colored widgets, that is, to associate a widget with a color? </p>
  
  <p>For example, is there any way to color the buttons of <code>buttons.ml</code> different colors without hardcoding based on location?</p>
