A6 (1996) brake pad thickness warning light?

Does anyone know what thickness of brake pad kicks off the warning light? Am I correct in thinking that there is initially a yellow warning light at one thickness and then a red warning light at a
lesser thickness?

No. The warning light is either off or on. Just two states, depending on whether the brake pad sensor has closed the circuit or not. Unfortunately I do not know at what thickness the warning comes on, but depending on how you drive, you should still be able to do another couple of thousand miles before the pads begin to damage your rotors.
Cheers,
Pete

If it's even close to it and one day you slam on your brakes it will set it off. See if you have brake dust around your wheel, meaning abundance of it. You'll clean it off and two day later it's dirty again. That means there wearing at a higher rate. Mine where flaking around the edges.

No, there is only the red light when the brake warning circuit is disconnected, the warning is also set if the wiring is defective.
On older models the circuit made ground connection, but by faulty wiring / connectors the warning system was disabled.
