Color affects mood


We all know that color plays a big important role in conveying information in nonverbal ways, not to mention that color can also affect moods, feelings, and emotions. According to the artist Pablo Picasso, “colors, like features, follow the changes of the emotions,” therefore, it can be said that color can also be considered as one of the powerful communication tools for signal action, influence mood, and influence physiological reactions. Color can make us happy, sad, anxious, or relaxed. However, what is color psychology, and how does each existing color has a different impact on the people who see it?

The psychology of color is based on the mental and effect colors have on sighted people in all facets of life. Researchers and experts have revealed that the psychology of color has effects on moods, feelings, and behavior. But it also needs to be remembered that there are variations in interpretation, meaning, and perception between different cultures.

For example, white is often interpreted as purity but in Eastern countries, white is seen as a symbol of mourning. Even though colors are somewhat subjective perspective, some colors have universal meanings, such as warm colors like red, orange, and yellow, these colors are often considered can evoke emotions like warmth and comfort even anger and hostility. Meanwhile, cool colors including blue, purple, and green are often associated with calm feelings like sadness.

It has been common knowledge that color is often linked with a person’s emotions as it could influence a person’s mental or physical state. Research revealed a small effect of red color to physiological impact is that it could seem to raise heart rate whereas blue can lower it. Therefore, color is believed to give a big impact that in 2009, blue lights were installed at the platforms of Tokyo’s Yamanote railway line to reduce the number of suicide incidents there.

The attempt to reduce the incidence of suicide after installing the blue lights came to success as the number fell by 74 percent at the stations where the blue lights were installed. The same attempt was also applied at Gatwick Airport train platforms. These actions were taken based on the affirmation that blue-colored lights could make people less impulsive and give calming senses, regardless of the little amount of scientific evidence to support this claim.

Color in the products that we purchase is also believed to tell about personality as our color preferences might describe the type of image we want to project and other people to see. Other factors such as age and gender can also influence the color choices we make. For example, if you choose white as your color when you purchase a phone, car, and many other things, it can evoke a sense of youth and modernity.

For black, people often describe it as sexy, powerful, and mysterious and for red, it can show that you’re a confident person. These are just some of the examples from other unmentioned colors. With all of this being said, color can convey information and give impressions for people who see it. Experts have indeed found that color can influence how we act even though it’s subjective and based on situational factors. However, more wide and deep scientific research regarding color psychology is needed to give us a better understanding and innovative discovery of color for the people in the future.

Recently, I discovered that one of our Big Ten Rivals, the Iowa Hawkeyes, has their away football locker room painted completely pink. Intrigued by this, I wanted to deeper research to discover how the color of the environment around you affects how your mood or energy level reacts.


Iowa first painted their locker room pink in 1979. Since then, it has been an icon for Iowa football.

According to, the color pink represents compassion, nurturing, and love. When an athlete is trying to get pumped up for a football game, being compassionate, nurturing, and loving is the last thing these athletes want to be. In a room, that is so overwhelmingly pink, it is hard to not let these phycological tricks get to you. If I were an athlete preparing for a game in this locker room, I couldn’t help to just laugh. The entire thing is so comical, but it actually works. Also, the color pink alleviates feelings of anger and resentment, two things every football player should have when playing another team.

To find out whether or not Iowa’s win record was overwhelmingly better at home compared to away, I went through every season since the locker room was painted and counted the wins and losses when playing at home, and the wins and losses when playing away.

Out of 452 games played since 1979, the Hawkeyes overall record is 274 wins and 178 losses. Of those wins and losses, 156 wins and 78 loss were at home. That leaves 118 wins and 100 losses were away. The Iowa Hawkeyes have a win percentage of 66.7% at home and a 54.1% win percentage while away. This is over a 10% win percentage difference from playing their football games in their home stadium versus playing their football game at an away stadium.

Although the win percentage is so much better at home than away, there are other variables that need to be considered. It is a well known fact that teams always play better in front of their home crowds than away, so this could be a large factor that influences win percentage other than the pink locker room. According to Sports Algorithm Research, home college football teams win 59.97% of the time and away teams win 40.03%. Thus, Iowa’s win percentage is roughly 6% better at home than other division one college sports teams. Another variable that must be considered is the quality of talent of the Iowa Hawkeyes football players versus their opponents. If the quality of athletes is much better for the Hawkeyes, that will have a huge impact of who will win the game regardless of color of locker room or where the game is taking place.
