What If Pain Had a Color?

By Carol Levy, PNN Columnist

What if your pain had a color? Not a color picked to honor an awareness day or month, but an actual color?

I could walk into the doctor's office. “I understand you have pain. Where is it located?” he’d ask. I’d point to the area. It was a bright chartreuse, as blinding as a neon sign.

“Oh yes. You definitely have pain. Let's see what we can do about that,” the doctor would say.

Wouldn’t that be simpler, easier? Unfortunately, it isn’t.

After the trigeminal neuralgia pain started near my eye, I was referred to a neuro-ophthalmologist. Our first meeting did not go well. The level of pain, the resulting disability, and its effect on me made it hard to tell my story in a calm and thoughtful way.

Stopping to collect my emotions, gather my thoughts and make sense of what made no sense, I started and stopped, my words coming in fits and starts. I struggled to control my emotions and not cry.

After a few minutes he stopped me. “Stop being so schizophrenic in how you're telling me your story,” he said. “Your pain is the result of anxiety.”

I didn't understand what he meant. No pain like mine could just be the result of nerves. He wrote a prescription for an anti-anxiety drug, but that only increased my stress, and the anger I felt towards the pain and medical profession.

Undaunted and with hope unfettered, I kept the next appointment. Again, he listened. He still seemed unimpressed with my pain and my story. But his interest was piqued by a birthmark on my forehead directly over the area of the pain. He noticed it would turn a brighter shade of red during various times of the appointment.

I was prissy back then. I hated cursing and embarrassed easily. He was not averse to using profanity, and just one or two words was too much for me. When he cursed, the birthmark would turn bright red. That changing of color and in the way my pain was triggered changed his feeling about my pain. He seemed more interested in it.

“I think it's time we bring you into the hospital,” he told me.

In those days, a doctor at a teaching hospital would be trailed by medical students, interns and residents. Like goslings imprinting on their mother, they followed the doctor everywhere.

When the group came to my room, the doctor wanted them to see how and when the birthmark changed color. He explained to them it was an outward sign of a neurovascular birth defect that he believed was the cause of my pain.

It was a teachable moment and the doctor liked milking it. He knew how easily I was embarrassed and how that would change the coloring of the birthmark. To get it to turn bright red, he jokingly threatened to expose himself (this was in the 1970’s). Immediately it changed color. I was so embarrassed.

It got to the point where all he had to say was, “I'm going to…” And like Pavlov’s dog, the birthmark turned bright red. He did that trick for his lot of ducklings, who were amazed.

My pain still did not have a color, but the changing color of the birthmark showed a visible, anatomic reason for it. It made my pain more real to others. If not for the birthmark and the trick of turning it off and on, the correct treatments might not have been tried.

Cancer patients have lumps or growths. Jaundice turns you yellow. Us? We have nothing but our word. Until pain has a color, our word has to be enough.

Seeing Red: How Colors Affect Pain

By Dr. Lynn Webster, PNN Columnist

It is a myth that the matador’s red cape -- the muleta -- incites rage in the bull and causes him to charge. The truth is, all cattle are colorblind.  The bull does not charge because of the color, but because of the movements of the matador and his cape.

It is not a myth, however, that color can affect the moods of humans. Researchers have studied how colors affect psychological states, such as anxiety, in people.

We now know that color also affects how people perceive pain. In this month’s issue of Pain Medicine, authors Karolina Wiercioch-Kuzianik and Przemyslaw Babel present “Color Hurts: The Effect of Color on Pain Perception,” exploring how color can affect the perception of pain.

A 2007 study reported more intense pain when a painful stimulation was preceded by a red color than a blue one. The new study builds on that work through two experiments.

In the first, 30 volunteers were shown six colors, one at a time, followed by mild electric shocks to their forearms – seven shocks with each color.

The participants, who knew in advance what the research would involve, reported their pain on a scale of 0 to 10 following each stimulation.

A black image was the control to which all the colors were compared. Black was chosen as the control because it is regarded as the absence of color.

The investigators found that the color red produced the most intense pain, followed by green and blue. Other colors were associated with less pain.

The results are not necessarily intuitive. Red may bring people joy when it takes the form of blooming roses, succulent berries, or wonderful memories of Christmas. But in this study, red increased pain levels.

The second experiment was designed to assess whether colors would affect the expectation of pain and pain intensity. Participants viewed a color and then received a series of mild electric shocks. Again, pain intensity was rated higher with some colors, particularly with red, blue and green. The investigators did not observe that specific colors influenced the participants' expectation of pain intensity.

Much has been written about how and why colors can affect our cognition and behavior. Our reactions to colors seem to be a result of biology and cultural imprinting. Interestingly, many people are aware that individuals supposedly have a “personality color.” Human resource professionals have even used color personality tests to assess job applicants.

Our folklore and traditions bestow certain meanings to colors. Snow White represents purity and innocence, while Edgar Allen Poe used a black raven to symbolize death. The Great Gatsby and other stories use the color gold to suggest greed.

Colors affect us psychologically and physically. As the authors of the Pain Medicine study concluded, colors can also influence our perception of pain. Thus, it may be important for researchers and clinicians to recognize that a patient's reported pain could be affected by the colors of the exam room or even the ambiance of a clinic.

It may be time to for people in pain to consider how their choices of clothes, furnishings, and even paint and wallpaper may factor into their levels of comfort.
