People use special names for colors.
One group made a way to name them. They wanted everyone to use the same names. This helps people in art and science.
There are 13 basic color names. Some names add more detail. You can use words to change a color. This makes 267 different color names.

People use many names for colors. One group made a way to name them all. This is the ISCC–NBS system.
Two groups worked together to make this system. They started in the 1930s. They wanted a way for everyone to use the same names. This helps people in science, art, and industry. It stops each job from making its own names.
The system has 13 basic color groups. Ten of these are hue names. Hue is the name of a color, like red or blue. Three groups are neutral colors. You can add extra words to these names. These words are called modifiers. Using these words makes 267 different color names.
Each color name fits into a special block. These blocks are parts of a color space. The blocks do not overlap. This means every color fits into exactly one block. The blocks look like a piece of pie with a bite taken out.
In 1955, the NBS made a color dictionary. It helped link many different color systems together. This made it easier for people to understand each other.
Have you ever tried to describe a color to a friend? It can be quite hard to pick the right word. The ISCC–NBS system was made to solve this problem. It is a special way to name colors using set terms. This system helps people in many different jobs talk about color. Scientists, artists, and factory workers can all use the same names.
This stops every industry from making up its own confusing names.
The system works by using a set of basic categories. There are 13 basic color categories in total. Ten of these are hue names, which are names like red or blue. The other three categories are neutral colors. You can also add modifiers, which are extra words, to these names. By combining a hue name with a modifier, you can create 267 different categories.
Not every modifier works with every hue, though. For example, you cannot have a "brilliant brown."
This system was first built in the 1930s. Two groups worked together to create it. One group was the Inter-Society Color Council, or ISCC. The other group was the National Bureau of Standards, or NBS. The ISCC was made of people from many American trade groups. In 1939, the system was published in a special journal.
The ISCC formally approved the system at that time.
Each color name fits into a specific "block" of space. These blocks are part of the Munsell color system. The blocks do not overlap each other. This means every single color falls into exactly one block. The shape of these blocks is very interesting. They look like a piece of pie with the point bitten off.
In 1955, the NBS published The Color Names Dictionary to help people. In 1965, they also published Centroid Color Charts.
You might see these color ideas in your daily life. The system helps define colors for things like plastic and paint. It is also used for building materials and even soil. Scientists use it in fields like botany and geology.
In 1976, a book called Color: Universal Language and Dictionary of Names was published. This book is the main source for the system. It helps keep color names organized for everyone to use.
The ISCC–NBS system is a standardized method for naming colors. It was created to provide a common language for describing color across many different fields. Without a standard system, different industries might invent their own names for the same shade. This can cause confusion in science, art, and manufacturing. The system allows experts to communicate clearly and accurately. It ensures that a color described in one place means the same thing in another.
This system works by dividing the world of color into specific blocks. These blocks are located within the Munsell color system. The Munsell system uses three dimensions to define color: hue, value, and chroma. Each ISCC–NBS category is represented by a block in this color space. These blocks are shaped like a sector of a right cylindrical annulus. You might imagine this as a piece of pie with the center point bitten off. These blocks are non-overlapping. This means every single color point falls into exactly one specific block. However, colors that fall precisely on the edges between blocks can sometimes be ambiguous.
The structure of the system relies on a backbone of 13 basic color categories. Ten of these are hue names, which are names like red or blue. The other three are neutral categories. The system also includes 16 intermediate categories that sit between the basic ones. To create even more specific names, you can combine a hue name with adjective modifiers. By doing this, the system can reach 267 named categories. Not every modifier works with every hue, though. For example, the system does not use the term "brilliant brown" or "very deep pink."
The history of the system began in the 1930s. It was a joint effort between two major groups. The Inter-Society Color Council (ISCC) consisted of delegates from various American trade organizations. The National Bureau of Standards (NBS) was a United States government agency. In 1932, the first chairman of the ISCC suggested a goal for the system. He wanted a way to name colors that was usable by science and art. He also wanted it to be understood by the general public. In 1939, the approach was published in the Journal of Research of the National Bureau of Standards. At that time, the ISCC formally approved the system.
Over the following decades, the system continued to evolve and grow. In the 1950s, the system was redefined to match new Munsell coordinates. This happened after the Munsell system was altered by renotations in 1943. In 1955, the NBS published The Color Names Dictionary. This book helped by cross-referencing terms from other color systems and dictionaries. In 1965, the NBS released Centroid Color Charts. These charts used physical color samples to show the central color in each category. Later, in 1976, a definitive source was published. It was called Color: Universal Language and Dictionary of Names. This book combined and updated previous works from the NBS.
The significance of the ISCC–NBS system is seen in its many applications. It provides a basis for systematizing color definitions in many industries. It is used in fashion and printing to ensure colors match. It is also used in botany and geology to describe natural colors. The system helps define standards for plastics and building materials. It even helps describe the colors of paint and soil. By providing these standards, the system prevents different industries from using incompatible color systems. This makes scientific and industrial work much more efficient.
One interesting aspect of the system is how it relates to other measurements. In the late 1940s, creators measured other color standards. They used spectrophotometric measurements or visual references to the Munsell Book of Color. This helped create a common frame of reference for many different charts. The system also relates to the Universal Color Language. This is a more general system for color designation. It can range from 13 broad, generic categories to extremely precise numeric values. These precise values come from spectrophotometric measurements. This allows the system to connect simple names to complex scientific data.
