The color blue is one of the most popular colors loved by people across cultures and generations. When we look around us, various shades of blue delight our visuals, ー blue sky, blue ocean, and even blue eyes.

Blue is one of the three primary colors. It sits between violet and green on the color wheel. Popular shades of blue are royal blue, pastel blue, dark blue, midnight blue. The hex code for color blue is #0000FF.

The history of blue

Some evidence shows that humans started developing blue colorants about 5,000 years ago. For example, the semi-precious stone Lapis Lazuli, a deep-blue metamorphic rock, was highly prized among the Egyptians.

During the Renaissance, this bright blue mineral was often combined with other ingredients, which led to the development of the pigment ultramarine ー the most expensive of all pigments. Afterward, blue dyes were spread worldwide and are widely used for arts, fashion, and more.

The color was initially called and described as wine-dark instead of blue. While we are all familiar with the shades of blue in our present times, let’s take a look at some of its early names from a thousand years ago.

Egyptian Blue

  • The Egyptians were making complex combinations of certain limestones, sand, and minerals to produce a beautiful opaque blue glass.

Ultramarine (Lapiz Lazuli)

  • The semi-precious stone Lapis Lazuli, a deep-blue metamorphic rock, was highly prized among the Egyptians.
  • During the Renaissance, the bright blue mineral initially invented by Egyptians was often combined with other ingredients, which led to the development of the pigment ultramarine ー the most expensive of all pigments.

Prussian Blue

  • It is believed that it was mixed and matched by dye-maker Johann Jacob Piesbach while working on some pigments and accidentally came into contact with animal blood.
  • Famous painters like Jean-Antoine Watteau, Katsushika Hokusai, and Pablo Picasso used this color extensively in their world-class paintings.

International Klein Blue

  • In 1960, a French artist named Yves Klein favors the color blue and exclusively used it throughout his artistic career.
  • Klein created a matte and brighter version of the ultramarine pigment in Paris, which he called ‘International Klein Blue’ or IKB.
  • It is used in spray painting objects and ancient sculptures which are displayed and sold in art galleries.

Afterward, blue dyes were spread worldwide and are widely used for arts, fashion, and more. Synthetic blue pigments replaced organic dyes in the 19th century. Soon after, dark blue was used for military uniforms, and in the 20th century, it was one of the most popular colors for business suits.

Blue is the color of trust. It suggests loyalty and integrity, which is why it is a great choice for businesses that want to project dependability, security, and peacefulness, such as financial companies.

Different hues of blue in branding and advertising can help manifest all the positive aspects of the color. In addition, it helps in building customer loyalty, which appears to be beneficial for small business owners.

Scientifically speaking, we see colors based on the light it absorbs from the color spectrum. The existence of the color blue in nature usually relies on chemistry, physics, or a combination of both sciences.

Blue Flowers

Did you know that blue flowers don’t really exist? The blue flowers we see are a combination of plant pigments and minerals combined with light. In fact, plenty of what we call ‘blue flowers’ are actually blue-toned purple, lavender, or even a cool-toned red.

Blue Animals

Blue animals on the other hand rely on physics to create a blue appearance. Certain animals that have rich blue hues are blue butterflies, peacocks, and a few other animals. Some are even using their blue hue to warn the predators while some rare sea creatures are like blue lights that are switching from time to time.

These are tricks that nature does for us to see the beauty of the color blue. It doesn’t really matter how it exactly happens. What’s important is that we enjoy what we see, which is indeed a reward from nature.

Blue is currently considered one of the most demanding colors for web designers. Because of its common use, it has become too ordinary over time.

Combining blue with different shades of grey can make a website look high-tech and sleek. Lighter shades of blue are mostly used for websites that are about health and wellness, travel, relaxation. Patriotic organizations, legal firms, sports team usually use darker shades.

Blue is frequently used for social media logos. One reason for that is that blue represents intelligence, communication and trust. In fact, out of all the colors on the color wheel, blue is by far the most trustworthy one. That is one of the main reasons why blue is a popular choice in marketing.

  1. I consider myself to be a blue, but romance is something I do not have in me. So am I still a blue? And for those wondering, lack of romance has been and will be quite convenient for me, due to constant hard work (filming, teaching, researching, editing, philosophy, and a make-the-world-a-better-place project). On a side note, the psychology of colors is quite interesting to me, and I hope to incorporate it into more of my work.

      1. Hello Matthew C,
        It I true, we are struggling with the same thing, I’ve had three break-ups, I’ve been accused of being more formal than romantic, and that is interpreted as not being in love or as not being caring.
        I have my projects to make the world a better place, but it is not an excuse for not being romantic, I just find it proper that there’s time for everything, and I don’t know how to act except to be cool and orderly.
        Being blue is fun except when you do a mistake of falling in love.

  2. Hello. I am in 9th grade. I have been researching about color psychology for 2 years. There is this one thing that I am deeply curious about, that I cannot find the answer to.

    When I went around information (your site as well), I found many saying that the color blue showed emotions of peace and trust, and I agree with it since blue is the color a lot of insurance and bank companies use.

    However, when I surveyed 60 people from my school, almost all of them answered that when they see blue, it reminds them sadness and restless. They also said green gives them the feeling of safety and trust.

    Could you tell me why there is a huge difference as written above between professional researches and individual ideas?

    I need to make a report to submit for school.

    Thank you!

    1. Hi Mona,

      I think the main factor is context. In terms of logos and brand identities, blue reflects a cool professionalism. However, if it is just on its own or used as the main color in a painting or larger work of art, that “sedating” effect can be amplified and it can cause a more serene, solemn or in some cases sad feeling. In fact, the word “blue” is sometimes used as a synonym for sad.

      The saturation level of color plays a role, too. Bright blue or a pleasant sky blue tend to have a more cheerful effect, while a muted or grayish-blue can be more sedating and introspective.

      Hope this helps!

  3. Thanks for the article on blue, which is one of my favorite colors. I noticed that a lot of companies in the pharmaceutical and medical industry use blue, green, and white. I’m guessing this is because they all have such a strong connotation with being related to healthcare in someway. However, I’d be interested to know if there are any clinical tests that show how people positively respond to these different colors.

    1. Hi Blissful,

      Yes, numerous studies have been done about human color responses. One marketing study found that color helps to improve brand recognition by up to 80 percent. Studies about the color blue have linked it with creativity and tranquility. Researchers believe this is due to the associations of blue with the sky, the sea and relaxing feelings. Blue is also perceived as “competent,” which would be valuable to a healthcare company’s image.

      Also, numerous studies have shown people experience green as calming and connected with nature, health, sustainability and durability, while white is associated with freshness, cleanliness and hope. It’s no wonder that these colors are so often used in healthcare industry marketing.

  4. A study says that with blue rooms you have better sleep quality. But which blue? Sky blue? Navy blue? Royal blue? Or any blue?



  6. I have read that only 7% of receptors in our eyes are blue sensitive which are S Cones and other L and M cones are Red and Green sensitive.

    The question is if our eyes are only 7% sensitive to blue how do we see every blue so loud and clear. Why don’t we miss any?

    Does this practically make all humans dichromatic?

  7. I’m blue da ba de da be di da ba de da ba di
    I’m blue da be de da ba di da ba de da ba di da ba di da ba di

  8. Thanks it’s very usefull for me to know my friend personality so i want to say thanks for the good information

    Sorry if my english is not so good
    Couse i from indonesia(14 years old)

  9. I love blue and always have. This definition sums me up almost completely except for the social aspect and having close friends. Besides my lover/husband/best friend, I need my good friends and love to socialize a few times a month. Otherwise blue is me!!!!!

  10. Well, my favorite color is Blue and Gray and I also found out what color gray means in your site from your article color blue is what really my personality is, I often use in my things and in my room is the Sky blue color. But then I search for Gray because it’s my favorite color too and I always match it with my things and clothes, and even furniture. Then I fount out as I analyze it that the personality of color gray is contradiction to the personality of color blue. Lol hahah! But then psychologically I conclude that I am naturally a person who is blue but trying hard to be a gray? And yeah i found myself like this…

    Im sociable but sometimes I am admiring those people who are not sociable. I’m a person always surrounded by my friends and I can’t live without it. But then sometimes I just want to be alone and be quiet for some reasons. Most of the time I am open to everyone but again there’s area in my life that I don’t want to share, need of privacy. I envious the people like gray because they can be alone, but I can too if I will. but most of the time I’m not.

    Therefore I conclude. I’m a person who is Blue and want to have a person in my side like Gray. ^_^

    I will find a person like Gray. This is my totally opposite character. hahah!! Thank you for this, my friend. It helps a lot! ^_^ Godbless you!

  11. Blue represents both the sky and the sea, and is associated with open spaces, freedom, intuition, imagination, expansiveness, inspiration, and sensitivity. Blue also represents meanings of depth, trust, loyalty, sincerity, wisdom, confidence, stability, faith, heaven, and intelligence.
