  <p>I have tried replacing <code>color</code> with <code>item</code> but the error message is this one:</p>
  
  <blockquote>
    <p>Error:Error: Unsupported node 'item'
    Error:Execution failed for task ':app:mergeDebugResources'.
    C:\Users\X\AndroidStudioProjects\X\app\src\main\res\values\styles.xml: Error: Unsupported node 'item'</p>

  <p>This is my "style.xml" file:</p>
  
  <pre><code>    &lt;resources&gt;
       &lt;color name="colorPrimary"&gt;#21222c&lt;/color&gt;
       &lt;color name="colorPrimaryDark"&gt;#21222c&lt;/color&gt;
       &lt;color name="colorAccent"&gt;#fff&lt;/color&gt;
       &lt;!-- blue style gradient --&gt;
       &lt;color name="bluestartcolor"&gt;#47f9fe&lt;/color&gt;
       &lt;color name="blueendcolor"&gt;#1295fd&lt;/color&gt;
       &lt;!-- orange style gradient --&gt;
       &lt;color name="orangestartcolor"&gt;#feed64&lt;/color&gt;
       &lt;color name="orangeendcolor"&gt;#dda660&lt;/color&gt;
       &lt;!-- pink style gradient --&gt;
       &lt;color name="pinkstartcolor"&gt;#fd75a5&lt;/color&gt;
       &lt;color name="pinkendcolor"&gt;#ea1e77&lt;/color&gt;
       &lt;!-- purplle style gradient --&gt;
       &lt;color name="purplestartcolor"&gt;#f75fe1&lt;/color&gt;
       &lt;color name="purpeendcolor"&gt;#c425ec&lt;/color&gt;
       &lt;!-- green style gradient --&gt;
       &lt;color name="greenstartcolor"&gt;#b4fa51&lt;/color&gt;
       &lt;color name="greenendcolor"&gt;#78cb59&lt;/color&gt;
      &lt;/resources&gt;
  </code></pre>
  
  <p>And this is my "colors.xml" file:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;resources&gt;
   &lt;color name="colorPrimary"&gt;#21222c&lt;/color&gt;
   &lt;color name="colorPrimaryDark"&gt;#21222c&lt;/color&gt;
   &lt;color name="colorAccent"&gt;#fff&lt;/color&gt;
  &lt;/resources&gt;
  </code></pre>
