title: Coloring the Intersection of a Venn Diagram
body: <p>I've been struggling for a while with coloring in only the intersection of a Venn Diagram and wondering how I can do that. Just one color to be filled to white didn't help.</p>
  <pre><code>  Intersection_of_A_and_B &lt;- venn.diagram(x = list(&quot;A&quot; = 1:100,
                                                       &quot;B&quot; = 96:140),
                                              category.names = c(&quot;A&quot;, &quot;B&quot;),
                                              filename = NULL,
                                              fill = c(&quot;palegreen4&quot;, &quot;white&quot;),
                                              alpha = 1,
                                              fontface = &quot;bold&quot;,
                                              fontfamily = &quot;Courier&quot;,
                                              cat.fontface = &quot;bold&quot;,
                                              cat.fontfamily = &quot;Courier&quot;) 
      
      grid.arrange(gTree(children = Intersection_of_A_and_B), 
                   top = &quot;Intersection of A and B&quot;)
  </code></pre>
  <p>Additionally, is there any way for me to change the title to be in the same font as my categories as well?</p>
