Munsell color theory
During his study of color, Munsell realized the need for an organized way of defining colors. He wanted to create a system that had a meaningful notation of color, rather than just color names that he found were "foolish" and "misleading".
He set out to create his color space in 1898. To do this, he used his unique inventions to help make measurements to organize his system. One of these inventions was the
photometer
A photometer is an instrument that measures the strength of electromagnetic radiation in the range from ultraviolet to infrared and including the visible spectrum. Most photometers convert light into an electric current using a photoresistor, ...

of an object, and Munsell used this to make measurements of different colors and to help define how color changes. This information would later become his three dimensions of color. He also patented an invention called the "Spinning Top".
This device was similar to the rotating color wheel developed by
James Maxwell, where several colors were placed on the top and the top was spun, mixing the colors together. Munsell used this device to measure the relationship between chroma and value, which helped him create templates for each step in chroma and value for every hue. With these tools, Munsell was able to define three dimensions that define color. He also paid close attention to the sensitivity of the human

, and considered this when creating the steps between colors in his system, particularly his value scale. He called these dimensions Hue, Value, and Chroma.

Hue
In color theory, hue is one of the main properties (called color appearance parameters) of a color, defined technically in the CIECAM02 model as "the degree to which a stimulus can be described as similar to or different from stimuli that ...
is the attribute of color by which we distinguish red from green, blue from yellow, and other colors. Munsell chose several colors to be the principal hues. These are Red, Yellow, Green, Blue, and Purple. These hues were arranged in a circle. Each hue can be mixed with the same amount of the neighboring hues to create intermediate hues: yellow-red, green-yellow, blue-green, purple-blue, and red-purple. Each color can be defined by how much of each principal hue it contains. A color that is composed of just a principal hue would be given a number 5. So, the red primary would be given the number 5R. If you move to the left of the red hue, the number increases, with the color exactly in between red and yellow-red defined as 10R. Continuing around the circle, the number of the color goes back down to 1YR right after 10 red, until the color is composed of just the yellow-red primary, in which case the color would be 10YR. So, the number represents how much of the primary hue the color contains.
Munsell Value defines the
lightness of a color, or how much black or white the color contains. The neutral color scale, from black to white with neutral greys in between, all have a hue of 0, which means they do not contain any hue. Instead these colors only change in value. Black would have a value of 0N, with N designating value. White would have a value of 10N, and middle grey would have a value of 5N. A grey in between middle grey and black would have a value of 2.5N. This value scale is based upon visual experiments. The middle grey is visual perceived to have equal amounts of black and white, and so on for other greys. It was very important for Munsell to create a system that was based on the human visual response to color.
The final dimension created was
chroma. Before the Munsell color theory, chroma was not a term used in the art or scientific community. Instead, the intensity of color was defined as
saturation
Saturation, saturated, unsaturation or unsaturated may refer to:
Chemistry
* Saturation, a property of organic compounds referring to carbon-carbon bonds
**Saturated and unsaturated compounds
** Degree of unsaturation
**Saturated fat or fatty aci ...
. However, Munsell felt it appropriate to break up saturation into two different dimensions, namely value and chroma. Chroma defines the difference between a pure hue and a pure grey. So, a color with a chroma of 1 would be very close to a grey. It is important to note that the maximum chroma of a color is defined by the hue of the color. For example, a color with a yellow hue will have less chroma values than a color with purple hue. This is because of the human visual sensitivity to different hues. Again, this shows how the human

is modeled through the Munsell color theory.
With each of the dimensions defined, it is now possible to distinguish a color based on its Munsell Notation. Take for example the color 2.5YR 3/4. This color is between red and yellow-red, but closer to yellow-red, has a value of 3 which is closer to black, and has a chroma of 4.
Munsell also wanted to create a standard way of measuring and viewing color. To do this, he investigated the relationship between the color and the light source used for
illumination. In short, he found that the light source used drastically effected the color perceived. To help in this investigation, Munsell visited the
Edison Light Company. He eventually developed the standard for daylight viewing of colors for accurate color evaluation.

, Munsell created the
Munsell color system
In colorimetry, the Munsell color system is a color space that specifies colors based on three properties of color: hue (basic color), chroma (color intensity), and value ( lightness). It was created by Professor Albert H. Munsell in the first ...
. It is set up to organize each color by the color's hue, value, and chroma. Each dimension of a color can be changed independently of the other dimensions.
This helped Munsell organize the colors in a three-dimensional space, known as the Munsell Color Space. To create this space, Munsell first took the neutral colors, and aligned them vertically, with black on the bottom and white on the top. In between, the neutral greys were spaced out in equal visual intervals. So, as one moves up in the space, the value of each row increases. Next, Munsell organized the chroma as increasing away from the center. So as one gets farther away from the center, the chroma increases. The hue is positioned at different angles protruding away from the center neutral colors. The distance between each color was visually uniform, because the system was derived from vigorous testing of the human visual response to color. This arrangement turned out to be known as the Munsell color tree.
![Munsell-system](https://upload.wikimedia.org/wikipedia/commons/d/d5/Munsell-system.svg)
By organizing the Munsell color system in this way, the Munsell tree has many advantages. One advantage is that the system is designed for new colors to be added. If the spacing between two colors is too large, an intermediate color can be placed in between those two colors. What is important is that adding new colors this way will not disturb the order of the other colors. In other words, the other colors' dimension values will not change. Another advantage of this system is that it made it very easy to communicate color. Each color is given its own values, which can be thought of as coordinates in the space. Therefore, to communicate color, the coordinates of the color can stated, and the exact color will be known. So, the Munsell color system created a standard system of color specification.
It also proved to be the groundwork for many other color spaces, such as
CIELab. This is because Munsell did much of the pioneering work in Color Science, and other systems expanded on what he already discovered.
However, there are some limitations to the Munsell color system. While it is handy to have a system with visual uniformly spaced colors, the space is not continuous, meaning that it has a discrete number of samples. Also, the spacing between the colors are very large, and because of this it is difficult to measure thresholds using the system, such as the just noticeable difference. These limitations inspired the
CIE to develop a uniform, continuous color space for characterizing color differences. This turned out to be the
CIELab color space, which was heavily influenced by the Munsell color system.
A few changes were made to the System since it was first developed. in 1943, the
OSA recommended a change in the notation of the system, and these changes became known as the Munsell re-notations. In 1950, the number of hues in the ''Munsell Book of Color'' doubled from 20 to 40. Then in 1958, a glossy version of the ''Book of Color'' was produced in addition to the matte version already in print.
Color education
One of Albert Munsell's goals in life was to standardize the way color was taught to children. Primarily, he wanted to focus on Grades 4 through 9. During September and October 1904, Munsell met with Miss Peterson, the Superintendent of Drawing for Boston, and Mr. Pritchard, Master of the Everett School in Boston, and worked with them to create the Color Education Primer. The Color Education Primer was created around the principles of Color Theory. It established the education of where colors come from, how they can be measured, and how they can be compared and organized. Munsell described the goals of the primer as to teach children to, "...describe a color (locates), relate the color to others, writes by a notation, names, harmonize and find them." Later, these objectives became the ground work for creating the Munsell Book of Color. Munsell, Peterson, and Pritchard agreed on the primer to help demonstrate the "rules" of the Munsell Color Theory.
Today, the Munsell Color Theory still stands as the basis of color education. It provides a simple, meaningful way to describe colors and organize them. Many companies, such as

Bridge between art and science
With his work in creating a systematic way of defining color, Albert Munsell created a necessary bridge between art and science. His color order system has enough structure to allow scientists to expand upon and use it, while being simple enough for artists with no scientific background to use it for selecting and comparing colors. Munsell's System essentially created a way of communicating color. Munsell wanted the study of color to be similar to the study of

.
In music, one can simply hear a note and how it relates to other notes based on the position of the note on the staff. Munsell wanted it to be possible to see a color based on three dimensions. This would describe a color and relate that color to other colors. These dimensions were also designed so that they could be understood by artists and scientists alike. It should be observed that in creating these dimensions, Munsell used many different fields of science, such as

. This relates the idea to color to not only science and art, but to different fields within science as well.
![Munsell Books](https://upload.wikimedia.org/wikipedia/commons/1/12/Munsell_Books.jpg)
Along with his scientific intuition, Munsell's artistic background influenced his choice of the three different dimensions to describe color. This particularly applies to chroma. Before the Munsell color system existed, the term chroma also did not exist. However, the term
saturation

did exist among the art community. The saturation of a color described how pure and how bright a color was.
Munsell saw this as being two different dimensions, and decided to break it up into two different dimensions, chroma and value. To support his new idea of chroma, Munsell consulted several scientists on how it should be properly defined. They all agreed that chroma was a new term. One of these scientists was Dr. House from

theory. He also noted that "the physicist is busy with spectral hues, but the physiologist, like the painter, is busy with the sensation."
This again shows how art and science rely on each other in the world of color.
Munsell continued to gain support from other scientists for his new color space. He visited
