1, I added a 'temperature' param,
// gray brightness adjustment Default=100(less=darker/more=brighter)
gray += (temperature - 1.0);
Let me know if it does what you want?

Not really sure how do implement this. I'm still trying to get my head around the basics!
Somebody reading this post might be able to add this?
Feel free to edit/ change the effect to suit.
