+   The actual colors to be used are configured using the environment variable
+   <code class="envar">PG_COLORS</code><a id="id-1.11.15.5.2.2" class="indexterm"></a>
+   (note plural).  The value is a colon-separated list of
+   <code class="literal"><em class="replaceable"><code>key</code></em>=<em class="replaceable"><code>value</code></em></code>
+   pairs.  The keys specify what the color is to be used for.  The values are
+   SGR (Select Graphic Rendition) specifications, which are interpreted by the
+   terminal.
+  </p><p>
+   The following keys are currently in use:
