title: log4net coloredConsoleAppender not showing any color
body: <p>I am trying to configure log4net to log coloured text to the console with the following settings.</p>
  
  <pre><code>&lt;log4net&gt;
    &lt;appender name="ColoredConsoleAppender" type="log4net.Appender.ColoredConsoleAppender"&gt;
      &lt;mapping&gt;
        &lt;level value="ERROR" /&gt;
        &lt;foreColor value="Red" /&gt;
        &lt;backColor value="Green" /&gt;
      &lt;/mapping&gt;
      &lt;mapping&gt;
        &lt;level value="DEBUG" /&gt;
        &lt;foreColor value="White" /&gt;
        &lt;backColor value="Green" /&gt;
      &lt;/mapping&gt;
      &lt;layout type="log4net.Layout.PatternLayout"&gt;
        &lt;conversionPattern value="%date %-5level [%thread]  %logger [%property{NDC}] - %message%newline" /&gt;
      &lt;/layout&gt;
    &lt;/appender&gt;
  
    &lt;!-- Set root logger level to DEBUG and its only appender to ColoredConsoleAppender --&gt;
    &lt;root&gt;
      &lt;level value="DEBUG" /&gt;
      &lt;appender-ref ref="ColoredConsoleAppender" /&gt;
    &lt;/root&gt;
  &lt;/log4net&gt;
  </code></pre>
  
  <p>However, the error logs are not coming out as red color. What might be the issue?</p>
