How do I make python use this random generated color?

So as of now, I have this code;

import turtle
import random

def getColor():
    selection = random.randint(1,3)
    if selection == 1:
        return "green"
    elif selection == 2:
        return "red"
    else:
        return "blue"

def drawPerson(my_turtle, x, y):
    my_turtle.penup()
    my_turtle.goto(x,y)
    my_turtle.pendown()
    my_turtle.pensize(3)

    xul.color = getColor()
    print(xul.color)
        if xul.color == "green":
            xul.color("green")
        elif xul.color == "red":
            xul.color("red")
        else:
            xul.color("blue")

    xul.forward(90)
    xul.left(90)
    xul.forward(90)
    xul.left(90)
    xul.forward(90)
    xul.left(90)
    xul.forward(90)
    xul.left(90)


xul = turtle.Turtle()
drawPerson(xul,150,150)
drawPerson(xul,-150,150)
drawPerson(xul,-150,-150)
drawPerson(xul,150,-150)
drawPerson(xul,0,0)

The problem is.. I can generate the color, it prints the color it draws all the shapes, but I cannot figure out how to make the color actually get applied to the turtle before it draws. I have tried things like;

xul.color("getColor")

and numerous other things, but I cannot seem to figure it out.. If someone could just give me the line of code that I am missing I'd greatly GREATLY appreciate it! Thanks!
