Is January a bleak, colorless time of the year where you live? To brighten your gray winter days, we’ve asked Jeopardy! phenom Ken Jennings to poke holes in four of your most embarrassing misconceptions about color. After all, there are plenty of colorful anniversaries to observe this month. The first color TV broadcast was the Rose Bowl of January 1953, and in January 1993, Crayola added sixteen new colors to its crayon boxes, including “Tickle Me Pink” and “Macaroni and Cheese.” The political novel Primary Colors was a January release; so was Radiohead’s album In Rainbows. Could there be a better time of year for a kaleidoscope of facts that—however colorful—are completely wrong?

Color Myth #1: Bulls See Red When They See Red.

For over three hundred years, Spanish matadors have used a red cape called the muleta in the final match of a bullfight, beckoning the angry bull onward with deft motions of the cape. The color red does in fact have a strong physiological effect on humans, elevating blood pressure, respiration, and brain activity, so it’s not much of a stretch to believe the old myth that the color red gets bulls riled up as well.


The only problem with this is that bulls are colorblind. Some animals have excellent color vision—monkeys, squirrels, and many fish can see color almost as well as humans. Insects like butterflies and bees can even see colors we can’t, with vision well into the ultraviolet part of the spectrum. But cattle are about as colorblind as you can get: they see all colors as varying shades of gray. That red cape could be blue or green or puce, and they’d charge anyway.

Why do they charge? As a wise woman once said, it’s not the color of the dye; it’s the motion of the fabric. The flapping of the cape is what gets the bull’s attention. It’s only red to help the audience in the cheap seats see the action, and to hide all the blood. Not to go all PETA here or anything, but I used to live in Spain and bullfights are pretty brutal. By the time the matador emerges with his red cape, the bull has already been mauled by two mounted riders with lances and three sidekicks armed with barbed sticks. Under those unhappy circumstances, you’d charge at the skinny Latin guy in the sparkly suit too, no matter what color his little flag was.

Quick Quiz: What American author wrote the 1932 bullfighting classic Death in the Afternoon?

Ken Jennings is the author of Brainiac, Ken Jennings's Trivia Almanac, and Maphead, out now. He's also the proud owner of an underwhelming Bag o' Crap. Follow him at ken-jennings.com or on Twitter as @KenJennings.

It's a really good book too. Recommended!

Hi, I'm one of the writers. My powers are limited but I'll do what I can.

Didn't Hemingway write all the books about bullfighting in the '30s?

Bulls aren't color blind. They have two kinds of cone receptors making them dichromatic.

"Not to go all PETA here or anything"

You better be careful, Ken; if people think you're squeamish about torturing animals, you'll lose all credibility.

Some interesting work has been done debunking the idea we have only five senses, and debunking many ideas about each of those senses.

SIGHT
Quick - how many types of photoreceptors do humans have? Just rods and cones? Here's a wiki for you:
http://en.wikipedia.org/wiki/Photoreceptor_cell
Of course, you can read the journal articles if you want better writing.

TASTE
Salty, sweet, sour and bitter, right? Nope. There's at least one more, and decent arguments for another one or two taste sensations.

OTHERS
You get the idea. The point is, saying bulls or dogs are monochromatic or dichromatic, or making just about any other scientific pronouncement, should be followed by either "we think" or "as far as we know now."

When rich or powerful people propose a change, it is designed to make them richer or more powerful.

I stand corrected! My original source was wrong...I've tracked down some studies from the 1990s suggesting that cattle are actually BETTER at distinguishing between blue and green than any other pair of colors (for night vision, scientists think) so I couldn't have chosen a worse example of bull color-blindness than "blue, green, or puce."

That said, they're completely red-green color-blind, so the red might as well be some much cooler color. They don't care.

You have control of the board, make the next selection!

You can just tell already that it's going to be a good Wednesday.

I strongly suspect Woot! of waiting for me to hop in the car and head home from work every time they've got some Random Crap to throw up.

Okay, I don't follow Ken on any social media (except the woot blog here) and have no idea if y'all have seen it yet... but today's XKCD comic is pretty good, with quite the alt-text stinger at the end!

So flattered! My not-really-a-response was:

Hemingway was the right answer to the trivia question, by the way. Well done.
