The longest wavelength of light humans can see is around 750 nm, deep red. If we were to observe a green-colored space probe approaching a stellar black hole of 20 solar masses, how close to the event horizon would it be when it just turned invisible? Green light has a wavelength around 520 nm. Penalty factor 10%
