THE CREATIVE CODING START

HERE IS MY INITIAL STARFIELD CHALLENGE AND ITS CODE:

THE STARFIELD CHALLENGE

For the Coding Challenge I chose the *1 Starfield in Processing. I was told to add a new function based on the challenge and draw a flow chart of the new function. I chose to add a function of color change through setting a sort of a timer on the code. I would like the code to run for 30 seconds before it changes the color of the background. I believe it will work quite well because the colors would make the piece more vibrant and exciting, rather than the dullness of the black and white space. Following the initial and final sketches, I will be making an 'if statement' flow chart for my added function.

var colors = ['c70000', '3dc700', '082bc7'];
var active = 0;
setInterval(function(){
document.querySelector('body').style.background = colors[active];
active++;
if (active == colors.length) active = 0;
}, 30000);

I want to have this function in my Coding Challenge, but for now it is not working and I am in the process of figuring out WHY!?
