READ THIS NEXT: Wearing This Color Instantly Makes You More Attractive, Studies Show. People have been using fashion as a form of self-expression for centuries. And it’s not only what we wear but the color we’re wearing that turns out to have one of the most potent effects. “The color of our clothing serves as a signal to others; it tells them who we are,” fashion company The Good Trade explains. Susan Gagnon, a fashion expert and the editor-in-chief of Costumes Heaven, tells Best Life that the concept is central to one field of study: color psychology, which seeks to determine how certain colors impact human behavior. “Our brains are wired to sensory triggers with emotions. Some triggers incite happiness, others sadness,” Gagnon explains. “As such, different colors get different emotional reactions from us, such as trust.” Thankfully, you don’t have to spend your own time trying to figure out which color is associated with higher levels of trust—because researchers have already pinpointed the answer in a recent study. If you’re looking to gain the trust of those around you, it could come down to the color of your shirt.ae0fcc31ae342fd3a1346ebb1f342fcb Researchers from the Soochow University in China recently sought to “explore the influence” of clothing colors on the perception of trust, publishing their findings in the International Journal of Engineering Research & Technology (IJERT) in May 2021. The researchers gathered 32 participants and had them rate the level of trust they felt towards a digital figure wearing the same business suit photoshopped into different colors: red, yellow, green, blue, purple, orange, yellow-green, blue-green, and blue-purple. According to the study, the color blue, followed by blue-purple, were seen as the most trustworthy. “Those who wear blue and purple clothes get higher trust evaluations,” the researchers wrote.

David Lee, a color expert and retail interior designer, says that colors such as a blue and purple are likely to make other people see us as more trustworthy because there are “positive associations” with these hues. For example, the color blue is often associated with the sky, which is “calm and serene,” according to Gagnon. “So when people see others wearing blue, their brain associates it with the calmness of the sky,” she says. According to Lee, traits such as calmness and serenity can increase the security people feel in others. “This helps create trust and you get a feeling of security. It conveys reliability,” he explains. Of course, you can choose to wear blue in important situations, like during a job interview. But your natural attraction toward certain colors actually does say a lot about who you really are. “The colors you choose to wear represent your inclinations,” Gagnon says. “We unconsciously pick colors that match our personalities.” The IJERT study also pinpointed the color of clothing that received the lowest trust evaluation: green. This hue is “generally associated with motivated and ambitious people,” according to Gagnon. Although that might sound like a good thing, it’s likely to make people see you as very self-motivated—which doesn’t always lay the best foundation for trust. As Lee notes, the color green is also often linked with more explicitly negative traits such as deception and greed. Jessica Kats, a fashion expert and lifestyle writer at Soxy, reiterates that the hue is associated with jealousy and envy. “People consider it an untrustworthy color in many cultures and traditions,” she explains.
