Colors come in a wide variety in the world. You can find color everywhere, whether you’re observing the sky, plants, or other living things. As a result, certain colors are bound to look similar when there are many different hues in nature. You must learn to discern between them because there are so many hues that look like different tones of the same color. Three such shades that are similar and difficult to differentiate between are indigo, violet, and occasionally purple. You will discover the distinctions between purple and indigo in this post, as well as between violet, indigo, and purple.

Meaning of the Word “Indigo”

Indigo is a color. You must have at least once encountered the color indigo in this extravagantly colored world. According to the dictionary, indigo is a hue that resembles a deep reddish-blue or deep purplish-blue. However, the term “indigo” refers to more than just color. The plant that yields indigo dye is also known by the name “indigo.” The most well-known natural dye in existence is this one.

What is an Indigo Crop?

The plant known as the indigo crop, or Indigofera Tinctoria, is a member of the pea family. The natural dye indigo that it produces as a byproduct is well known. During the colonial period, indigo was the King of Dyes. Indigo is known as “Blue Gold” because of its reputation, much like petroleum. Although the indigo crop has been grown for over 4,000 years in Africa and India, it gained popularity during the period of European colonialism. As a result, the crop has a difficult, sometimes dark, history because the British sought to have a monopoly on the production of indigo. Due to slavery and other forms of exploitation, this goal forced the manufacture of indigo.

India became the world’s top producer of indigo during this time. India is still one of the world’s top producers of indigo today. In addition to being non-polluting, the indigo crop improves soil quality by reintroducing nitrogen. It is a multi-seasonal crop because the indigo plant grows all year round.

How is Indigo Color Made?

According to general agreement, indigo is either a deep reddish-blue or deep purplish-blue hue. The two types of colors are primary and secondary colors. Primary colors are the basis for all secondary hues. Indigo is a secondary hue that is even present in a rainbow.

The two primary hues, red and blue, can be combined to create indigo. In order to make indigo, red and blue must be combined so that there are three parts of blue for every one component of red. Red, however, is a color that stands out. According to this, blue will be present in a greater amount in direct proportion to red’s intensity. By adding black or white appropriately, you can further adjust how dark or light your indigo shade is.

What Are The Uses of Indigo?

Indigo has uses beyond only serving as a natural dye. Beyond the textile business, indigo is a multifaceted commodity with many applications. Although it also has a place in the agricultural sector, its main applications are in safety and medicine. Indigo has the following applications:

  • The textile industry uses indigo primarily as a natural or synthetic color. To color cotton yarn for use in the production of textiles, businesses employ indigo. Denim is a form of cotton fabric, and indigo is what gives denim jeans and jackets their characteristic colors.
  • The pea family includes the crop known as Indigofera tinctoria. Indigo is a leguminous crop, like the majority of pea crops. Because they replenish the nitrogen in the soil, legume crops are good for the environment. Because of this characteristic, indigo is a valuable transitional crop between two major crops, increasing crop productivity.
  • Unexpectedly, indigo also acts as a flame retardant. According to historical accounts, indigo-dyed cloths were used to battle fires in ancient Japan.

Additionally, indigo has therapeutic uses, including

  • Being bacterially neutral
  • Being the primary component in indigo tea
  • As a nematicide, combating plant parasites,
  • Taking care of scorpion bites
  • Taking care of the common cold,
  • Liver purification
  • Cleansing the blood.

Is Violet the Same Color as Purple?

Let’s first examine how purple differs from violet before examining the distinctions between indigo and violet or purple and indigo. Indigo and purple are both mixtures of the main colors, red and blue. Purple and violet, therefore, seem to be comparable.

  1. Purple is a color that people perceive. It suggests that we are able to distinguish the color purple because of our education rather than because it is a component of the visible light spectrum. It has a more saturated appearance than violet and is a blend of exactly equal parts blue and red.
  2. Between violet and indigo light, there is a region of the light spectrum called violet. It is a less intense shade in which blue predominates over red.

As we’ve seen, the main distinction between violet and purple is that they exist. Seven hues make up the visible light spectrum: violet, indigo, blue, green, yellow, orange, and red. Purple is therefore not included in this range. Because violet is a member of the light spectrum and a natural extension of white light, we identify purple as a perceived color.

Purple, indigo, and violet are hence not separated into indigo and violet, but are three distinct colors. The fact that all three colors are a mixture of red and blue makes them appear similar. Each hue, however, necessitates a varied ratio of red and blue, giving each color its distinctive shade.

In the Rainbow, What Color is Violet?

A region of the electromagnetic spectrum of light is violet. So what makes violet and indigo different from one another? It lies between indigo and ultraviolet light. Due to the splitting of white light, a rainbow, one of nature’s most stunning occurrences, also exhibits violet. One of the white light’s seven individual colors is represented by each letter. By chance, violet is the color that lies just beneath the indigo stripe and is the innermost hue in a rainbow.


The location of indigo and violet on a rainbow provides another distinction between them. Indigo lies between blue and violet light, while violet is between ultraviolet and indigo light. Indigo, which comes after violet and before blue, is the second-to-innermost color on a rainbow.
