[ExI] The color Brown

[John Clark]

There is no such thing as brown light. You will never see a brown LED. You
will never see a brown LASER. You will never even see a brown pixel on your
computer screen. You may object to that and say you've seen brown images on
your screen all the time, and that's true but what you've really seen is
dim orange areas on the screen that your brain interprets as brown, and you
only know it's dim because of the context. The orange needs to be
surrounded by something much brighter. Like all colors (and like everything
else) brown needs contrast, but that fact is most easily demonstrated with
brown.

There is a very good video on this subject:

Incidentally the fruit "orange" didn't get its name because of its color,
instead the color got its name because of the fruit. Before the 16th
century when orange trees were brought to Europe there was no specific name
for that color, people just called it yellowish red.
