How to fire an Event when webcam recognize a specific color? I am working with tracking.js please take a look.. I try some like this:.

[CODE title="Fire event"]Var (r,g,b).
Var event-name = Event.event-name
If r>240; g<20; b<20. Function ()... fire('event_name');[/CODE]

<!doctype html>
<meta charset="utf-8">
<title>tracking.js - first tracking</title>
<script src="tracking-min.js"></script>
<video id="myVideo" width="400" height="300" preload autoplay loop muted>
<source src='zuck.mp4' type="video/mp4" />
<button id='on' >Tracker on</button>
<button id='off'>Tracker off</button>
var _t = null;
$(document).ready(function() {
//var ct = tracking.ColorTracker
tracking.ColorTracker.registerColor('green', function(r, g, b) {
if (r == 0 && g == 250 && b == 0) {
return true;
return false;
tracking.ColorTracker.registerColor('black', function(r, g, b) {
if (r < 50 && g < 50 && b < 50) {
return true;
return false;
var colors = new tracking.ColorTracker(['magenta', 'cyan', 'yellow','green']);
colors.on('track', function(event) {
if (event.data.length === 0) {
// No colors were detected in this frame.
} else {
event.data.forEach(function(rect) {
console.log(rect.x, rect.y, rect.height, rect.width, rect.color);
tracking.track('#myVideo', colors);
