Title is not entirely clear what is required if more detail is: In mysql db table has, from it to the page of data is displayed in html table this code:

<?php            
   $db_host = 'localhost';         
   $db_name = 'DB';         
   $db_username = 'NAME';         
   $db_password = 'PASS';       
   $db_table_to_show = 'TABLE';         
   $connect_to_db = mysql_connect($db_host, $db_username, $db_password) 
   or die("Could not connect: " . mysql_error());           
   mysql_select_db($db_name, $connect_to_db)      
   or die("Could not select DB: " . mysql_error());   
   mysql_set_charset("utf8");

   or die(mysql_error());            
   echo '<table id="table">';       
   echo '<thead>';         
   echo '<tr>';
   echo '<th class="table-fandom">fandom</th>';        
   echo '<th>author</th>';     
   echo '<th class="table-name">name</th>';
   echo '<th>size</th>';    
   echo '<th class="table-status">status</th>';             
   echo '<th>date</th>';       
   echo '<th>tags</th>';
   echo '</tr>';       
   echo '</thead>';        
   echo '<tbody>';         

   while($data = mysql_fetch_array($qr_result)){       
       echo '<tr>';
       echo '<td>' . $data['fandom'] . '</td>';    
       echo '<td>' . $data['author'] . '</td>';         
       echo '<td><a href="/goto/' . $data['url'] . '" target="_blank">' . $data['name'] . '</a><div class="menu" style="display: none;"><br> '                                             . $data['annotation'] .  '  </div></td>';       
       echo '<td>' . $data['size'] . '</td>';  
       echo '<td>' . $data['status'] . '</td>';        
       echo '<td>' . $data['date'] . '</td>';  
       echo '<td>' . $data['tags'] . '</td>';                  
       echo '</tr>';       
   }       

   echo '</tbody>';        
   echo '</table>';         
   mysql_close($connect_to_db);        
  ?>

Requires that the new records that were added today, has been assigned a special css class within 72 hours. PS Sorry for my english, it's not my native language.

You can do this:

...
 while($data = mysql_fetch_array($qr_result)){     
      if($data['date'] > date('Y-m-d', strtotime('-3 days'))  
          echo '<tr class="new">';
      else
          echo '<tr>';

      echo '<td>' . $data['fandom'] . '</td>';    
      echo '<td>' . $data['author'] . '</td>';         
      echo '<td><a href="/goto/' . $data['url'] . '" target="_blank">' .         $data['name'] . '</a><div class="menu" style="display: none;"><br> '         . $data['annotation'] .  '  </div></td>';       
      echo '<td>' . $data['size'] . '</td>';  
      echo '<td>' . $data['status'] . '</td>';        
      echo '<td>' . $data['date'] . '</td>';  
      echo '<td>' . $data['tags'] . '</td>';                  
      echo '</tr>';       
    }

First you need to add registration time in table. For example you save registration time in unix timestamp. Then you need to use condition after while loop.

 while($data = mysql_fetch_array($qr_result))
 { 
    if($data['registration_time'] > strtotime("-3 days") ) 
    {
      echo '<tr class="change_color_class">';
    }
    else
    {
          echo '<tr class="normal_class">';
    }        
 }
