javascript – building the value attribute of an option tag using jQuery

I have a function like this where I’m dynamically generating the option tag of a select.

function colorInfo(data) {
    console.log("Color Info");
    console.log(data);
    let colorData = JSON.parse(data);

    console.log(colorData);

    $.each(colorData, function (key, value) {
        $("#lineupColors").append(
        $("")
           .attr("value",'{"colorId":'+value.colorId+',"colorCode":'+value.colorCode+'}')
          .text(value.colorName)
      );
    });
  }

Since I am defining the value as a Json object, how can I add double quotes such that the value would look like {"colorId":"1","colorCode":"#FFFFFF"}.

Right now it is coming out like this – which is not a valid JSON :

{"colorId":1,"colorCode":#FFFFFF}.
