title: Set Quantmod chartSeries line color from green to another color
body: <p>Using version.string R version 2.11.0 (2010-04-22)
  quantmod   "0.3-17"<br>
  Windows XP</p>
  
  <p>When using the <code>chartSeries</code> function in <code>quantmod</code> with <code>type="line"</code> the line color that is displayed  on the chart is green. I would like to change the color from green to another color. </p>
  
  <p>It looks like  i can change the <code>chartTheme</code>, but the theme does not explicitly have a variable to change the color of the plot display for lines. </p>
  
  <p>I can change the line display color  when using the  <code>plot()</code> function -  So is it possible to change the display of line plots to a different color using <code>chartSeries()</code> in <code>quantmod</code>?</p>
