Setup

        Object.defineProperties(this, {
            // Have no choice but to add these methods to the instance
            name: {
                get: function () {
                    return name;
                },
                set: function (n) {
                    name = n;
                }
            }
        });
    }
    function PropertyColor(name) {
        this._name = name;
        Object.defineProperties(this, {
            name: {
                get: function () {
                    return this._name;
                },
                set: function (n) {
                    this._name = n;
