IveI've built aan accelerometer based dice. It changes colour based on what side of the dice faces up. All is well and good, except IdI'd like the rgbRGB to fade from one colour to the next instead of changes instantly.

Every fading example I have adopted has broken the code so far. I guess my initial code isntisn't set up for it. Any ideas for a workaround?
Thanks
