Create a button that changes strokeColor - Please help

Hi there, I'm new to processing and am trying to create a canvas in which you can edit and enhance a given image (roughly) using the draw Stroke tool and then save it at the end.
I've set up the scene so that there is my image on a background and I can draw on it. But I'd like there to be a button to change the Stroke colour from black to say, grey or any colour to be honest.
I was thinking I could just create a button and add a variable called colour and then 'on click' .push a value into the variable array like in Javascript. But I can't do it :/

Any suggestions would be absolutely great - I'd really appreciate it. Thankyou very much

This is the code I have to draw my character etc -
PImage img;

void setup() {

size(600,600);

background(#FF9999);

// Make a new instance of a PImage by loading an image file

img = loadImage("forprocessing.png");

image(img,0,0);

}

void draw() {

// Draw the image to the screen at coordinate (0,0)

stroke(0);

strokeWeight(2);

smooth();

// Draw if mouse is pressed

if (mousePressed) {

line(pmouseX, pmouseY, mouseX, mouseY);

}

}
