<p>
<code>set ccols <i>col1 col2 col3 ... colN</i></code>
<p>
Sets specific color numbers for contour levels specified by <a
href="gradcomdsetclevs.html"><code>set clevs</code></a>.
<p>
<h3>Usage Notes</h3>
<ol>
<li>
Contour colors are reset with every execution of <a
href="gradcomdclear.html"><code>clear</code></a> or <a
href="gradcomddisplay.html"><code>display</code></a>.
<li>User-specified ccols won't take effect unless clevs are also set.
<li>If any of the color numbers is < 0, it is set to 0 (the background color).
<li>(<span class="style1">Version 2.0.0+</span>) When using 'gxout shade2' or 'gxout shade2b', if any of the color numbers is < 0, the contour is not drawn (i.e., it is effectively transparent).
<li>See section of User's Guide on <a href="colorcontrol.html">controlling colors in Grads</a> for more details.
