This example: {"Gray": "11", "Black": "18"}
is an object, you can use the loop for..in . This will check all enumerated properties, including ancestor properties
var o = {
"Gray": "11",
"Black": "18"
};
for (var key in o) {
console.log (key, ':', o [key]);

Better to use jquery $ .each function
$. each (JSON.parse ('{"Gray": "11", "Black": "18 "} '), function (key, value) {
console.log (key + "" + value);
})

var json = '{"Gray": "11", "Black": "18 "} ';
// Convert JSON to object
var obj = JSON.parse (json);
// Working with the object
for (var prop in obj) {
console.log (prop, obj [prop]);

use the construction for..in
var data = {"Gray": "11", "Black": "18"};
for (color in data)
alert ("Color:" + color + ", Value:" + data [color];
