That must be what was in the all-black spaceship that Douglas Adams
described in _The Restaurant at the End of the Universe_:
"It's the wild colour scheme that freaks me," said Zaphod,
whose love affair with this ship had lasted almost three
minutes into the flight. "Every time you try to operate
one of these weird black controls that are labeled in black
on a black background, a little black light lights up black
to let you know you've done it. What is this? Some kind of
galactic hyperhearse?"
Elsewhere I once read a description of a Noise-Emitting Diode,
which would generate a loud (although brief) sound when you
hooked it up to 110 volts AC.
