is for coolant but you can do the same for everything in the car the Dye is harmless and is only a uv color so put some in there and top off the fluid while your at it and turn the steering wheel from lock to lock a few times and then put the glasses on and look for the dye. If its around where you fill it up it means the master cylinder is leaking and you'll need to replace it.
OH and get a bottle of this: https://www.amazon.com/Lucas-10008-Power-Steering-Stop/dp/B000ARPVNO and put it in with the rest of it. Hopefully it'll stop the leak all together and if not wait till the leak is at least dripping on the ground before worrying about replacing anything and just keep her topped off
