  29  <P> Colors can be specified in three different ways</P>
  30  <OL>
  31  <LI> By using one of the, roughly, 400 pre-defined color names, e.g<DIV class="phpscript">
  32  <CODE><FONT color="#000000"> <FONT color="#0000BB">&nbsp;SetColor</FONT><FONT color="#007700">
  33  (</FONT><FONT color="#DD0000">&quot;khaki&quot;</FONT><FONT color="#007700">);</FONT><FONT
  34  color="#0000BB"></FONT></FONT></CODE></DIV>
  35  <P> A named color can also be modified by adding a adjustment factor. An
  36   adjustment factor, 0 &lt; f &lt; 1, a smaller value will give a darker
  37   version and a value of 0 or 1 will return the original color. A value &gt;
  38   1 will make the color brighter. A few examples<DIV class="phpscript"><CODE>
  39  <FONT color="#000000"> <FONT color="#0000BB">&nbsp;SetColor</FONT><FONT color="#007700">
  40  (</FONT><FONT color="#DD0000">&quot;khaki:0.5&quot;</FONT><FONT color="#007700">
  41  );&nbsp;</FONT><FONT color="#FF8000">//&nbsp;A&nbsp;darker&nbsp;version&nbsp;of&nbsp;&quot;khaki&quot;
  42  <BR></FONT><FONT color="#0000BB">SetColor</FONT><FONT color="#007700">(</FONT><FONT
  43  color="#DD0000">&quot;yellow:1.2&quot;</FONT><FONT color="#007700">);&nbsp;</FONT><FONT color="#FF8000">
  44  //&nbsp;A&nbsp;slightly&nbsp;lighter&nbsp;version&nbsp;of&nbsp;&quot;yellow&quot;</FONT><FONT color="#0000BB"></FONT>
  45  </FONT></CODE></DIV></P>
  46  <P></P>
  47  </LI>
  48  <LI> By specifying a RGB triple, e.g.<DIV class="phpscript"><CODE><FONT color="#000000">
  49   <FONT color="#0000BB">&nbsp;SetColor</FONT><FONT color="#007700">(array(</FONT><FONT

  53  <P></P>
  54  </LI>
  55  <LI> By specifying the color as a hex string value<DIV class="phpscript">
  56  <CODE><FONT color="#000000"> <FONT color="#0000BB">&nbsp;SetColor</FONT><FONT color="#007700">
  57  (</FONT><FONT color="#DD0000">&quot;#A16BFF&quot;</FONT><FONT color="#007700">);</FONT><FONT
