title: How to change text color on p:growl according to severity?
body: <p>I need to change the text color on <code>&lt;p:growl&gt;</code> according to severity, any idea?</p>
  
  <p>I'm adding a programmatic growl in this method:</p>
  
  <pre><code>public void addMessageGrowl(Severity typeMessage, String detailMessage) {
       FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(typeMessage, "", detailMessage));
  }
  </code></pre>
  
  <p>After I invoke this method:</p>
  
  <pre><code>addMessageGrowl(FacesMessage.SEVERITY_FATAL, "Ocurrió un error al ejecutar la operacion");
  </code></pre>
  
  <p>I however, want to customize the text color on the growl.</p>
