by

Use dataType:"json" for json data

$.ajax({
     url: 'ajax.php', //This is the current doc
     type: "POST",
     dataType:'json', // add json datatype to get json
     data: ({name: 145}),
     success: function(data){
         console.log(data);
     }
});

Also in PHP 

<?php
  $userAnswer = $_POST['name']; 
  $sql="SELECT * FROM <tablename> where color="".$userAnswer.""" ;
  $result=mysql_query($sql);
  $row=mysql_fetch_array($result);
  // for first row only and suppose table having data
  echo json_encode($row);  // pass array in json_encode  
?>
