In Bay13 instructions for doing rear brakes he mentions
the blue rotor pictured may cause brake vibrations.
What is cause of the rotor to get the bluish tint?

Nice image of a porche brake running rather hot:

I suspect it this one might be off of a race vehicle.

Check the exhaust pipe on a motorcycle near the cylinder. They are blue. The heat generated by your brakes can make the disks turn red hot, like an electric burner on a stove. When metal gets this hot it is easy to bend. That's why torque is so important when tightning lug nuts, if one nut is too tight - warp.
