Blue electricity, or electric blue, is a vivid shade of cyan that represents lightning, electric sparks, and ionized argon gas. The term electric blue was first used in 1845 to describe the colour of ionized air glow produced during electrical discharges. In popular culture, the colour is associated with energy, action, excitement, and power. In recent years, the term blue energy has also been used to describe osmotic power, a novel method of generating electricity using saltwater and freshwater separated by a semi-permeable membrane.

What You'll Learn
Blue lightning in popular culture
Blue lightning, or lightning bolts that are bluish-white, are commonly observed in nature. They are also frequently depicted in popular culture, especially in live-action films and realistic video games. In these mediums, lightning bolts are predominantly blue, and sometimes, the bolts are depicted as very blue with no white visible. Alternatively, purple is added to the mix, resulting in a vibrant purple shade.
In popular culture, blue lightning is often used to represent danger and power. For example, in the manga version of Naruto, the lightning from ninjutsu is yellow, but the anime adaptation changes it to blue. Similarly, Enel's lightning in the manga "One Piece" is yellow, produced from his Devil Fruit powers, but it becomes blue in the anime adaptation.
Blue lightning also appears in superhero media. For instance, while Spider-Man's Electro typically throws bolts of yellow electricity, certain incarnations of the character veer into blue lightning territory. Additionally, Shazam! from the Marvel Family has yellow lightning, but Wonder Woman's Wonder Girl Cassie Sandsmark uses her lightning-generating powers to create pale yellow bolts.
In mythology, lightning has been viewed as a sign or part of a deity. For example, the Greek god Zeus, the Norse god Thor, and the Hindu god Indra are all associated with lightning. The ancient Etruscans even produced guides to divining the future based on the omens displayed by thunder or lightning, a practice called ceraunoscopy or aeromancy.

Blue energy and water
Blue energy, otherwise known as osmotic power, is a novel way to generate electricity by harnessing the natural difference in salt concentration between salt water and freshwater. A semi-permeable membrane separates a tank of saltwater and a tank of freshwater. The saltwater has a much higher salt concentration, causing molecules from the freshwater side to rapidly pass to the saltwater side, creating pressure that can be turned into electricity.
Blue energy is just one part of the energy/water nexus, with researchers also working on developing membranes for water treatment, creating devices to recycle fertilizer runoff, and processing urine to produce clean water and hydrogen.
In addition, blue energy may have applications in water splitting, which is the process of splitting hydrogen and oxygen to produce energy. By combining current semiconductors with a salt gradient power source, the necessary voltage to split water could be achieved.
The term "blue energy" may also evoke the image of electric blue, a bright and vivid shade of blue often associated with electricity, energy, action, and excitement. Electric blue is also the colour of the sky and the ocean, and it is thus commonly associated with peacefulness and tranquility.

Blue in colour psychology
Blue is a colour often found in nature, such as the pale blue of a daytime sky or the rich dark blue of a deep pool of water. This is perhaps why we often describe blue as calm and serene. Blue is also a colour that is rarely found in natural food sources, and human instinct tells us to avoid blue-coloured food as it can be a sign of spoilage or poison.
Blue is associated with feelings of calm and relaxation. It can help slow the heart rate and breathing, making it a great colour to surround yourself with for meditation and relaxation. Some airports have even started incorporating blue lighting and imagery in their terminals to help promote a sense of calm prior to flying. Blue is also often linked to creativity, and can help generate ideas even under pressure.
Blue is a colour that is cherished and celebrated throughout history, carrying significant importance due to its rarity and the expense associated with its production. The ancient Egyptians and Romans, for example, revered this colour, incorporating it into their clothing and artwork to reflect their social and cultural values. In the Middle Ages, the production of blue dyes, crafted from the precious stone lapis lazuli, was quite an expensive process.
Blue is also a colour that is universally favoured by people everywhere. It is often viewed as a non-threatening colour that can seem conservative and traditional. It is also associated with dependability and
Darker shades of blue are known to help improve how we solve problems and make decisions, while lighter shades aid in focusing on details while performing a given task.

Blue electricity in fashion
Blue electricity, or electric blue, is a vivid, bright shade of blue that is often considered close to cyan. The colour is associated with electricity due to its resemblance to lightning, electric sparks, and the colour of ionized argon gas. Electric blue is a popular colour in fashion, especially in menswear, and is considered one of the more masculine bright shades. The colour communicates energy, action, excitement, innovation, and power, making it a popular choice for innovative brands and applications.
In fashion, electric blue is a versatile colour that can be dressed up or down. For a more formal look, electric blue can be paired with white to create a sensible yet lively outfit. For a more casual look, electric blue can be paired with other vivid hues, such as bright orange-red, to create a dramatic palette. The colour can also be used as an accent colour to add a pop of colour to an outfit.
The colour electric blue was first recorded in English in 1845 and gained popularity in the 1890s. The colour has been featured in various forms of media, such as the Sherlock Holmes story "The Adventure of the Copper Beeches", where Miss Hunter is required to wear an electric blue dress. In the 1998 retelling of the original 1963 Superman story, Red/Superman Blue, Superman is temporarily deprived of solar energy and harnesses electricity, adopting a blue and white suit to prevent the energy from dispersing.
Electric blue is a popular colour choice for logos due to its association with trustworthiness and reliability. The colour is also believed to communicate peacefulness and tranquility as it is the colour of the sky and the ocean. However, it is important to note that the use of electric blue in restaurants, menus, and food branding is generally avoided as it is believed to suppress appetite.

Blue electricity in nature
Blue electricity, or "electric blue", is a vivid and eye-catching colour that is often considered close to cyan. The name "electric blue" comes from the ionized air glow produced during electrical discharges, and its meaning has broadened to include shades of blue that are metaphorically "electric" due to their intensity and vibrancy. In nature, the electric blue crayfish and electric blue gecko are named for their bright blue appearance.
The colour electric blue is created during electrical discharges when a gas, such as argon, becomes ionized and emits light. This process can produce a variety of colour emissions depending on the gases involved, but blue and purple are commonly observed in the troposphere where oxygen and nitrogen are the dominant gases.
In popular culture, electric blue is often associated with energy, action, excitement, and innovation. It is a popular choice for logos of innovative brands or applications, as it communicates power and reliability. Additionally, blue is the most popular colour among the public, possibly due to its association with peaceful and tranquil feelings evoked by the colour of the sky and the ocean.
In some fictional works, such as video games and comic books, blue electricity or lightning is often associated with villains or evil characters. For example, in the Kingdom Hearts series, the villains Xemnas and Vanitas use blue lightning, while the heroic characters Sora and Aqua use yellow lightning. Similarly, in the Guilty Gear video game series, Ky Kiske uses blue lightning for his attacks, in contrast to his flame-wielding red-coloured rival, Sol Badguy.
Beyond its aesthetic and symbolic value, the term "blue energy" refers to a novel concept in the field of renewable energy. Blue energy, or osmotic power, utilizes the difference in salt concentration between freshwater and seawater to generate electricity. By separating the two types of water with a semi-permeable membrane, the difference in salt concentration creates pressure that can be converted into electrical energy. This method leverages the natural occurrence of saltwater and freshwater on our planet to potentially provide a sustainable and eco-friendly source of electricity.
