Hint: You need to read a $serialized_badges JSON string (which we will get from the user table and convert it to a PHP array using json_decode() then perhaps a foreach() loop to compare against the current $color[] array.
Or, you can do all this in Javascript by storing the badge[] js array serialized in localstorage, which is how I would do it I think.... No reason to do this in PHP, so I think best to do in Javascript.
