The sticker reacts to heat conducted by the caliper, and is there to indicate to you if you're overheating your braking system as a whole, and is used preventatively to see if the caliper is being overwhelmed. An overheated caliper can become compromised (boiling fluid, softened metal, etc.)
Paint on the rotor tells you if you're overheating the the pad and rotor, and if you need more cooling for the friction surfaces.
The two are distinctly different in function, but work hand in hand as a system.
