Can Color Heal? The Answer May Surprise You.

Color is everywhere. It’s in our language (Color me impressed) and music (Color my world). It sparks curiosity: “When you and I see green, do we see the same green?” Some days, we feel blue. Others, we see red. Colors color our world. But can it also improve healing? Let’s explore. 

First, how does color interface with emotions? Sunlight is made up of every color in the rainbow, combining into white light. When sunlight hits a surface, it bounces back only certain colors to the millions of light-sensitive rods and cones in our retinas. These send a signal via the optic nerve to various parts of the brain, including the prefrontal cortex, which sits behind the forehead just above the eyes. The prefrontal cortex links the incoming image with memories and emotions, which is why different colors can make us feel.

For instance, green relaxes us. Blue feels tranquil and yellow links to optimism. But colors are also cultural. Red represents love and danger in the West but luck and prosperity in some Asian cultures. Color can also be nostalgic. For instance, a grandparent may always wear a bright yellow hat, so yellow evokes memories and happiness. And you might be more likely to paint the kid’s bathroom a sunny yellow without even a thought.  

So can color also heal?

At least one study says yes. The Central European Journal of Medicine conducted a randomized controlled trial to test the effect that colors painted on the walls in patient rooms had on surgery recovery outcomes. They studied 80 randomized patients who recovered in rooms either painted with bright, beautiful colors or in stale, white-walled rooms. They measured their self-reported depression levels and anxiety, along with their physical health through pain scales.  

The results: Psychological and physical scores were significantly better in color-decorated rooms, suggesting that color can improve healing and theoretically reduce recovery time. In every category, there was at least a small improvement. Amazing. Of course, this is one study based on anecdotal evidence. But it’s encouraging.

It reminds us how much environment impacts mental and physical well-being writ large. The study points out that frequent interruptions, noise, and bright lights were all components affecting the patient’s anxiety, stress response, and sleep. And that all types of stimuli can make or break patients’ overall experience and health outcomes.  

So, while color is certainly an influence, it’s just one part of design. It reinforces that every design decisions has lasting and sometimes profound impacts on our lives. And that’s true all the way down to color choices.
