An expert in color psychology shares which shades to wear to make a good impression, boost confidence, and more

According to Lewis, red is the color of action and physicality, and wearing it can give you energy when you're feeling exhausted or need an extra kick for a long day.

"It's the psychological primary color of the body, so it can help us wake up, keep our attention, and even increase our heart rate," she told Insider. "I like to wear this color when I'm really fatigued."

Red can also be a great color to wear when you need to keep things highly energized, like when you're working out.

If you're looking for balance in your daily life, orange is definitely the color to wear, according to Lewis.

Orange hues are most associated with a familiar home environment and may be able to keep the body calm and balanced.

"Since our body takes in orange light with a sunrise that helps wake everything up in a calm way, I like to use orange on high-stress days with a cozy sweatshirt," the color expert told Insider.

According to the expert, wearing yellow can make you feel happier.

"As the color that makes the rods and cones of our eyes the most excited, yellow is the psychological primary color of the nervous system," Lewis said. "It can help us feel joyful, hopeful, or even help us focus more on our future."

Yellow can be great to use when you want to add a pop of color to an outfit.

Blue is the psychological primary color of the mind, according to Lewis. Wearing it may be able to help bring down your heart rate and blood pressure.

Different shades of blue have different calming effects, the expert explained. Lighter blues have the tendency to make people think of vacations, leading to a freer mind. And darker blues can bring about deeper thoughts, which can also promote stillness and relaxation.

"It's an incredible color that can also make people feel more trust with you, so it's perfect to wear at work when meeting a new client or to calm a stressful situation," she said.

Pink is a color of comfort and softness, according to Lewis.

This makes it a good wardrobe choice when you want to feel comfortable and soft. It's also helpful when tapping into the more feminine side of things, the expert said.

For calming effects, you may want to incorporate more green into your wardrobe.

"Green is the psychological primary color that balances the other three: red, yellow, and blue," the expert told Insider.

In other words, green has the power to evoke a number of feelings within the body, which can bring people to a state of homeostasis.

"Too stressed? It will calm you. Down in the dumps? It will lift you up," Lewis said. "It's a calming color that helps us grow, and I love wearing it."

Lewis said violet is the last color in the visible light spectrum, and it's most associated with spirituality and relationships. Wearing purple has the power to help people connect to other people or things deeply, according to the expert.

"I love to wear purple when meeting new people, as it helps form a quick connection," she told Insider. "You can also wear it to tap more into your spiritual side."

"Different from pink, magenta was named after a bloody battle," Lewis told Insider, referring to a battle during the Second Italian War of Independence where French and Italian forces defeated Austria in Magenta, Italy.

Magenta is the color of revolution, she explained, helping to spark action on a more energetic level.

"Whether it's to introduce a new concept at work or go out on the town, I like to use magenta to help people feel a bit more bold and revolutionary," Lewis said.
