I believe the optimal temperature has more to do with pad temperature than rotor temperature, although obviously those are closely tied.
EDIT - Chris Mandell told me both rotor and pads need to reach (but not exceed) optimal temp range for best case performance.
His theory on the absence of discolouration on my front rotor is that I use it in more of an on or off manner whereas the rear likely spends more consistent time in use
I have ridden on some rotors that appeared to have been tie dyed in preparation for Woodstock. The pads were sometimes toast but the rotors lived on in my recollection. Perhaps not as effectively though.
