Wechat's problem, mine has not been able to change the color

this is how I assembled the message content of the template 

$data = '{
           "touser":"' . $open_id . '",
           "url":"*************",
           "template_id":"iESo6q4cZ3XRiYdcOSoA6EDhYn4HGYaLsHpKDaXo83M",
           "data":{
                   "first": {
                        "value":","
                   },
                   "keyword1": {
                        "value":"",
                        "color":"-sharpFF0000"
                   },
                   "keyword2":{
                        "value":"50",
                        "color":"-sharpFF7F24"
                   },
                   "remark":{
                        "value":"~"
                   }
           }
           }';

the message style of the template is as follows:

I don't know if I can help you ~

is the question of odd and double quotation marks very confusing, ha
