Do you feel anxious in a yellow room? Does the color blue make you feel calm and relaxed? Artists and interior designers have long believed that color can dramatically affect moods, feelings, and emotions. "Colors, like features, follow the changes of the emotions," the artist Pablo Picasso once remarked.

Color is a powerful communication tool and can be used to signal action, influence mood, and even influence physiological reactions. Certain colors have been associated with increased blood pressure, increased metabolism, and eyestrain. So how exactly does color work? How is color believed to impact mood and behavior?

What Is Color Psychology?

In 1666, English scientist Sir Isaac Newton discovered that when pure white light passes through a prism, it separates into all of the visible colors. Newton also found that each color is made up of a single wavelength and cannot be separated any further into other colors.

Further experiments demonstrated that light could be combined to form other colors. For example, red light mixed with yellow light creates an orange color. Some colors, such as green and magenta, cancel each other out when mixed and result in a white light.

If you have ever painted, then you have probably noticed how certain colors can be mixed to create other colors.

"Given the prevalence of color, one would expect color psychology to be a well-developed area," researchers Andrew Elliot and Markus Maier have noted. "Surprisingly, little theoretical or empirical work has been conducted to date on color's influence on psychological functioning,﻿﻿ and the work that has been done has been driven mostly by practical concerns, not scientific rigor."

Despite the general lack of research in this area, the concept of color psychology has become a hot topic in marketing, art, design, and other areas. Much of the evidence in this emerging area is anecdotal at best, but researchers and experts have made a few important discoveries and observations about the psychology of color and the effect it has on moods, feelings, and behaviors.

Your feelings about color are often deeply personal and rooted in your own experience or culture.

For example, while the color white is used in many Western countries to represent purity and innocence, it is seen as a symbol of mourning in many Eastern countries.

The Psychological Effects of Color

Why is color such a powerful force in our lives? What effects can it have on our bodies and minds? While perceptions of color are somewhat subjective, there are some color effects that have universal meaning.

Colors in the red area of the color spectrum are known as warm colors and include red, orange, and yellow. These warm colors evoke emotions ranging from feelings of warmth and comfort to feelings of anger and hostility.

Colors on the blue side of the spectrum are known as cool colors and include blue, purple, and green. These colors are often described as calm, but can also call to mind feelings of sadness or indifference.

Color Psychology as Therapy

Several ancient cultures, including the Egyptians and Chinese, practiced chromotherapy, or the use of colors to heal. Chromotherapy is sometimes referred to as light therapy or colorology.

Colorology is still used today as a holistic or alternative treatment.﻿﻿ In this treatment:

Modern Research on Color Psychology

Most psychologists view color therapy with skepticism and point out that the supposed effects of color are often grossly exaggerated. Colors also have different meanings in different cultures.

Research has demonstrated in many cases that the mood-altering effects of color may only be temporary. A blue room may initially cause feelings of calm, but the effect dissipates after a short period of time.

However, existing research has found that color can impact people in a variety of surprising ways:

Color Can Influence Performance

Studies have also shown that certain colors can have an impact on performance. No one likes to see a graded test covered in red ink, but one study found that seeing the color red before taking an exam actually hurt test performance.﻿﻿

While the color red is often described as threatening, arousing or exciting, many previous studies on the impact of the color red have been largely inconclusive. The study found, however, that exposing students to the color red prior to an exam has been shown to have a negative impact on test performance.

In the first of the six experiments described in the study, 71 U.S. colleges students were presented with a participant number colored either red, green or black prior to taking a five-minute test.

The results revealed that students who were presented with the red number before taking the test scored more than 20% lower than those presented with the green and black numbers.

Color and Consumer Purchases

Color psychology suggests that various shades can have a wide range of effects, from boosting our moods to causing anxiety. But could the color of the products you purchase ever say something about your personality? For example, could the color of the car you buy somehow relate to some underlying personality traits or quirks?

Your color preferences why buying items might say something about the type of image you may be trying to project. Color preferences, from the clothes you wear to the car you drive, can sometimes make a statement about how we want other people to perceive us. Other factors such as age and gender can also influence the color choices we make.

White : As many of our readers have suggested, the color white can feel fresh and clean. The color is often used to evoke a sense of youth and modernity.

High tech products are often silver, so the color is often linked to things that are new, modern, and cutting-edge.

Gray: The experts suggest that people who drive gray cars don't want to stand out and instead prefer something a bit more subtle.

Of course, the color selections we make are often influenced by factors including price, selection, and other practical concerns. Not only that, but color preferences can also change in time.﻿﻿

A person might prefer brighter, more attention-getting colors when they are younger, but find themselves drawn to more traditional colors as they grow older. The personality of the buyer can play an important role in color selection, but buyers are often heavily influenced by factors such as price as well as availability.

For example, purchasing a white vehicle might be less about wanting people to think that you are young and modern and more about the climate you live in; people who live in hot climates typically prefer light-colored vehicles over dark ones.

Additional Research Is Still Needed

Interest in the subject of color psychology is growing, but there remain a number of unanswered questions. How do color associations develop? How powerful is the influence of these associations on real-world behavior?

Can color be used to increase worker productivity or workplace safety? What colors have an impact on consumer behavior? Do certain personality types prefer certain colors? As researchers continue to explore such questions, we may soon learn more about the impact that color has on human psychology.

Zena O'Connor, a faculty member in the Department of Architecture, Design, and Planning at the University of Sydney, suggests that people should be wary of many of the claims they see about the psychology of color.

"Many of these claims lack substantiation in terms of empirical support, exhibit fundamental flaws (such as causal oversimplification and subjective validation), and may include factoids presented as facts," O'Connor explains. "In addition, such claims often refer to outdated research without referring to current research findings."

A Word From Verywell

Color can play an important role in conveying information, creating certain moods, and even influencing the decisions people make. Color preferences also exert an influence on the objects people choose to purchase, the clothes they wear, and the way they adorn their environments.

People often select objects in colors that evoke certain moods or feelings, such as selecting a car color that seems sporty, futuristic, sleek, or trustworthy. Room colors can also be used to evoke specific moods, such as painting a bedroom a soft green to create a peaceful mood.

So what's the bottom line? Experts have found that while color can have an influence on how we feel and act, these effects are subject to personal, cultural, and situational factors. More scientific research is needed to gain a better understanding of color psychology.
