A MakerBot TOM with attitude: RGB leds controlled by the status of the print process

This is an idea to implement a functional design into my bot using color fades to represent a status. I want to add some custom print codes so any help will be nice because I am pretty new into working with the MakerBot firmware, etc!

-Begin color -> to red (heating up)
-Red to Green fade (working, some extra effects maybe?, 2 or 3 steps between the print code)
-Green -> Light blue/blue (cooling, like the ABP cool down)
-Celebration colors now! :P and finally yellow or purple... or even XM
