The association of the colour blue with electricity is a result of how electricity interacts with electrons in the air. When electricity passes through the air, electrons gain energy and jump to a more excited state. As they return to their original energy level, they release a photon of light, which appears blue. This is because the air is primarily made up of oxygen and nitrogen, which emit a blue-violet colour when excited. The colour blue is also associated with feelings of peacefulness and tranquility, as it is the colour of the sky and the ocean. In colour psychology, blue is linked to trustworthiness and reliability, making it a popular choice for business logos.

- Blue can also represent sadness, as in the phrase feeling blue
- Electric arcs can cause a variety of colour emissions, but blue is typical in the troposphere due to the presence of nitrogen and oxygen
Blue is the colour of lightning and electric sparks
The reason why lightning and electric sparks appear blue is due to the way they interact with the electrons in the air. When electricity passes through the air, it excites the electrons in each air atom, causing them to jump to a higher energy state. As these electrons return to their original energy level, they release a photon of light. In the case of air, this photon appears blue, but other gases would produce different colours. For example, neon gas appears red or red-orange when excited by electricity.
The colour blue is also associated with trustworthiness, reliability, peacefulness, and tranquility. It is the colour of the sky and the ocean, which may contribute to these associations. However, blue can also be linked with sadness, as the phrase "feeling blue" suggests unhappiness.
The term "electric blue" was first used to describe a colour in English in 1845. The shade was originally named after the colour of the ionized air glow produced during electrical discharges. Today, the term "electric blue" can refer to a range of bright blues varying in intensity. In colour psychology, blue is a popular choice for business logos due to its positive associations.

The colour blue is trustworthy and reliable, making it popular for business logos
Blue is often associated with electricity, with shades like electric blue and cyan representing lightning, electric sparks, and ionized argon gas. The term "electric blue" was first used in 1845 and became popular in the 1890s, broadening to include intense and vibrant shades of blue.
The colour blue is also widely regarded as trustworthy and reliable, making it a popular choice for business logos. Blue has been consistently shown to be the favourite colour of both men and women worldwide, with people having mostly positive associations with it. The phrase "true blue" has been used for centuries to describe trustworthiness, and blue is often linked with credibility, reliability, and professionalism. This makes it a common choice for brands aiming to emphasise their authority and competence. For example, Pepsi uses blue in its branding to convey a fresh and reliable image.
Blue is also calming and reassuring, evoking feelings of tranquility, reassurance, and calmness. This makes it particularly suitable for brands in the health and wellness space, as it can help evoke feelings of relaxation and inspiration. The meditation app Calm, for instance, uses soft blue tones and ocean-inspired imagery to promote mindfulness and mental well-being.
Additionally, blue offers strong contrast on digital interfaces, improving readability, accessibility, and usability. This is beneficial for creating a positive and inclusive user experience, which is crucial for many businesses today.
The colour blue's versatility is another factor in its popularity for business logos. With a wide range of shades, each conveying distinct connotations and associations, businesses can choose the shade of blue that best aligns with their brand identity. For instance, a lighter blue, like sky blue or baby blue, can convey friendliness and tranquility, while darker shades can suggest reliability and authority.

Blue is the colour of the sky and ocean, so it's associated with peacefulness
Blue is the colour of the sky and the ocean, so it's often associated with peacefulness and tranquility. This association is so strong that the colour blue is commonly used to represent electricity, even though electricity itself is colourless.
When electricity moves through the air, it causes a reaction that creates light. The wavelength of light emitted by the particles in the air determines the colour we see, and since the air is primarily made up of oxygen and nitrogen, which emit a blue-violet colour, we tend to associate electricity with the colour blue.
This association is further reinforced by the colour of lightning, which is often depicted as blue. The colour electric blue, in particular, is said to represent the colour of lightning, electric sparks, and ionized argon gas. It was originally named after the ionized air glow produced during electrical discharges, but its meaning has since broadened to include any shades of blue that are metaphorically "electric" due to their intensity or vibrancy.
In popular culture, the association between electricity and blue is also perpetuated by media depictions of electrically-powered superheroes shooting blue lightning from their hands. Additionally, blue is often used in branding and logos to convey a sense of trustworthiness, reliability, and innovation, further solidifying the positive connotations associated with the colour blue.
While blue is indeed associated with peacefulness and tranquility, it's important to note that it can also evoke other emotions. For example, the phrase "feeling blue" is commonly used to describe a state of unhappiness or sadness. Nonetheless, the colour blue remains a popular and versatile choice, often favoured by the public for its calming and serene qualities.

Blue can also represent sadness, as in the phrase feeling blue
Blue can also represent sadness, as in the phrase "feeling blue". This is a common way to describe gloominess or sorrow. People typically feel blue for a reason, and these feelings usually tend to be mild and pass before too long. For example, someone might feel blue if they miss out on an opportunity, have a disagreement with someone close to them, or are unhappy with their life's state. When feeling blue, people may feel sad or tearful, want to spend time alone, and lack their usual energy or motivation. They may also experience temporary haziness, especially when thinking about whatever triggered their sadness, and may not have much of an appetite.
Although people with the blues might describe themselves as depressed, the blues and depression are not the same thing. While stressful events can trigger depression, people who are clinically depressed often feel unhappy even when their life is going well. If you suspect that you might be dealing with depression, it is important to seek help.

Electric arcs can cause a variety of colour emissions, but blue is typical in the troposphere due to the presence of nitrogen and oxygen
Electric arcs are electrical breakdowns of gas that produce a prolonged electrical discharge. They can cause a variety of colour emissions, depending on the gases involved. However, blue and purple are the typical colours produced in the troposphere, where oxygen and nitrogen are the dominant gases.
When an electric arc occurs in the air, it converts the air into plasma, a good conductor of electricity. In a plasma state, electrons constantly bind to and leave atoms. Each time an electron binds to an atom, it emits energy in the form of light. The colour of this light depends on the gas involved. For example, neon appears red or red-orange when converted into plasma.
In the case of air, which is composed primarily of nitrogen and oxygen, the light emitted is blue or purple. This is because the de-excitation of nitrogen and oxygen atoms, which are the primary components of air, results in the emission of blue or purple photons.
The association between the colour blue and electricity is also reflected in the term "electric blue," which refers to a bright, vivid shade of blue. This colour is often associated with energy, action, excitement, innovation, and power. It is also commonly used to represent lightning and electric sparks. Electric blue has been used in fashion, branding, and lighting, and its association with electricity has added to its popularity.
