Unable to set tr background-color with jquery

I am unable to change the background color of a table row with jquery.
It works with font color but for some reason not with the background color.

this works: $(this).parent('tr').css('color', 'red');

but this does not: $(this).parent('tr').css('background-color', 'green');

Any idea what I am doing wrong? I couldn't find a similar case on the internet.

$(document).on('click', "td", function(event) {
  $(this).parent('tr').css('color', 'red');
  $(this).parent('tr').css('background-color', 'green');
});
table {
  font-family: arial, sans-serif;
  border-collapse: collapse;
  width: 500px;
  margin: 50px 0 0 50px;
}

td,
th {
  border: 1px solid #cacaca;
  text-align: left;
  padding: 8px;
  background-color: #f5f5f5;
}

th {
  background-color: #dce0e3;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
  <tr>
    <th>Company</th>
    <th>Contact</th>
    <th>Country</th>
  </tr>
  <tbody>
    <tr>
      <td>Alfreds Futterkiste</td>
      <td>Maria Anders</td>
      <td>Germany</td>
    </tr>
    <tr>
      <td>Centro comercial</td>
      <td>Francisco Chang</td>
      <td>Mexico</td>
    </tr>
    <tr>
      <td>Ernst Handel</td>
      <td>Roland Mendel</td>
      <td>Austria</td>
    </tr>
    <tr>
      <td>Island Trading</td>
      <td>Helen Bennett</td>
      <td>UK</td>
    </tr>
    <tr>
      <td>Laughing Bacchus </td>
      <td>Yoshi Tannamuri</td>
      <td>Canada</td>
    </tr>
    <tr>
      <td>Magazzini Alimentari </td>
      <td>Giovanni Rovelli</td>
      <td>Italy</td>
    </tr>
  </tbody>
</table>

As you have given td background color #f5f5f5 that's why it's not happening. In jquery you are applying it to tr.

$(document).on('click', "td", function(event) {
  $(this).parent('tr').css('color', 'red');
  $(this).parent('tr').css('background-color', 'green');
  $(this).parent('tr').find('td').css('background-color', 'green');
});
table {
  font-family: arial, sans-serif;
  border-collapse: collapse;
  width: 500px;
  margin: 50px 0 0 50px;
}

td,
th {
  border: 1px solid #cacaca;
  text-align: left;
  padding: 8px;
  background-color: #f5f5f5;
}

th {
  background-color: #dce0e3;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
  <tr>
    <th>Company</th>
    <th>Contact</th>
    <th>Country</th>
  </tr>
  <tbody>
    <tr>
      <td>Alfreds Futterkiste</td>
      <td>Maria Anders</td>
      <td>Germany</td>
    </tr>
    <tr>
      <td>Centro comercial</td>
      <td>Francisco Chang</td>
      <td>Mexico</td>
    </tr>
    <tr>
      <td>Ernst Handel</td>
      <td>Roland Mendel</td>
      <td>Austria</td>
    </tr>
    <tr>
      <td>Island Trading</td>
      <td>Helen Bennett</td>
      <td>UK</td>
    </tr>
    <tr>
      <td>Laughing Bacchus </td>
      <td>Yoshi Tannamuri</td>
      <td>Canada</td>
    </tr>
    <tr>
      <td>Magazzini Alimentari </td>
      <td>Giovanni Rovelli</td>
      <td>Italy</td>
    </tr>
  </tbody>
</table>

Your code is correct, but you can't see background code assigned to tr because you have td {background-color: #f5f5f5;} style that paints over your tr.
