Sending parameters to a prototype in Javascript

Is it possible to send a parameter to a prototype to set new properties of an object? for example:

function person(first, last, age, eyecolor) {
this.firstName = first;
this.lastName = last;
this.age = age;
this.eyeColor = eyecolor;
}

person.prototype = function(color) {
    this.hair_color = color;
};

This may not have been implemented correctly, but my question is still the same. I am trying to make sure I understand prototypes so maybe I am missing a fundamental idea about them. It seems that everywhere I look prototypes are used to set defined variables as opposed to one that is input such as this

person.prototype = function() {
    this.hair_color = "brown";
};

Prototype allows you add new properties and correct way of doing that will be:

person.prototype.hair_color = "brown";
