The Obvious Choice
Candles are wicked, and incandescent lights, as you can tell
from the name, are really fragrance-free candles in disguise.
But fluorescent lights are green.
clue:
The eye adapts so well that most people don’t notice the greenness
of fluorescent lighting. You can see it clearly in the windows of
a building at night. It’s from a strong green line in the spectrum
of mercury, so they’re not green in the environmental sense....
take oh take this clue away
