How to change the color of a graph line when using comet function?

Hi everyone! I was wondering if there is any way to change the color of the line being generated in my code to a different color?

%% System Clearing
clc;
clear all;
close all;
%% Walking/step Conditions
stepsL=1;   %stepping to the left
stepsR=1;   %stepping to the right
%% Random Walking - 2500 steps
for n = 1: 2500
    x = rand ;
    if (x >= 0.5)
        stepsL = stepsL + 1; % if moving left
    else
        stepsR = stepsR + 1; % if moving right
    end
    location(n) = stepsL - stepsR; % location tracker for direction
end
comet(location)

[m,n] = size(Location) ;  % hoping Location to be m*2 array 
for i = 1:m
    plot(Location(1:i,1),Location(1:i,2),'color','r')
    drawnow
end
