title: How to specify color of multiplot title
body: <p>This might be a silly question, but I can't figure out how to specify the  (font-) color for the title in a multiplot.    </p>
  
  <pre><code>gnuplot&gt; set multiplot layout 2,1 title "Title" font ",14" tc rgb "blue"
                                                             ^
           invalid or duplicate option
  </code></pre>
