Changing row color doesn't affect sorted column

Inside my datatable I change a row's column with this:

$('#id12').closest("tr").css('background-color', 'red');

Row's background color changed to red. Except the column that is sorted.
That column's color is still the same.

Then I put an important tag, but it didn't change anything.

$('#id12').closest("tr").css('background-color', 'red', 'important');
