threex.coloradjust is a threex game extension for three.js. It provides a color adjustement in post processing. It happens on the whole screen and changes every colors giving a whole new ambiance to your games. It includes smooth transitions between each ambiance. There are 22 ambiances going from 'sepia', to 'thermal', or 'radioactive'. I highly recommend 'nightvision' if your game is about fps shooting at night! It is very flexible, you can build your own ambiance with any image editing software. It is ported from color-adjust demo by greggman. Here is a video where you can see greggman explaining the underlying technic. It explains how to do 3d texture in webgl! :)

You can install it via script tag

bower install threex.coloradjustIt build the passes for the color effect.
It exposes colorPass.colorPass for a THREE.EffectComposer instance.
Create an instance
var colorPasses = new THREEx.ColorAdjust.Passes();
Everytime you render the scene, be sure to update it
colorPasses.update(delta, now)
Then you add those passes to an THREE.EffectComposer like that
colorPasses.addPassesTo(composer)
