You can do this by using the random number generator we had learned earlier in the course. A color can be defined by its string value like 'red', hex value like #ff0000 or rgb value like (255,0,0). In this case we will be using the rgb values.

Here is the code: 

const myHeading = document.getElementById('myHeading');

let rgbColor = () => {
 return Math.floor((Math.random()*256));
};

let randomColor = () => {
  return "rgb("+rgbColor()+","+rgbColor()+","+rgbColor()+")"; 
};

myHeading.addEventListener('click', () => {
                           myHeading.style.color = randomColor();
                          });
