In colorimetry, the Munsell color system is a color space that specifies colors based on three properties of color: hue (basic color), value (lightness), and chroma (color intensity). It was created by Albert H. Munsell in the first decade of the 20th century and adopted by the United States Department of Agriculture (USDA) as the official color system for soil research in the 1930s.
Several earlier color order systems had placed colors into a three-dimensional color solid of one form or another, but Munsell was the first to separate hue, value, and chroma into perceptually uniform and independent dimensions, and he was the first to illustrate the colors systematically in three-dimensional space.[1] Munsell's system, particularly the later renotations, is based on rigorous measurements of human subjects' visual responses to color, putting it on a firm experimental scientific basis. Because of this basis in human visual perception, Munsell's system has outlasted its contemporary color models, and though it has been superseded for some uses by models such as CIELAB (L*a*b*) and CIECAM02, it is still in wide use today.[2]
Munsell determined the spacing of colors along these dimensions by taking measurements of human visual responses. In each dimension, Munsell colors are as close to perceptually uniform as he could make them, which makes the resulting shape quite irregular. As Munsell explains:
Desire to fit a chosen contour, such as the pyramid, cone, cylinder or cube, coupled with a lack of proper tests, has led to many distorted statements of color relations, and it becomes evident, when physical measurement of pigment values and chromas is studied, that no regular contour will serve.
Two colors of equal value and chroma, on opposite sides of a hue circle, are complementary colors, and mix additively to the neutral gray of the same value. The diagram below shows 40 evenly spaced Munsell hues, with complements vertically aligned.
Value, or lightness, varies vertically along the color solid, from black (value 0) at the bottom, to white (value 10) at the top.[5] Neutral grays lie along the vertical axis between black and white.
Several color solids before Munsell's plotted luminosity from black on the bottom to white on the top, with a gray gradient between them, but these systems neglected to keep perceptual lightness constant across horizontal slices. Instead, they plotted fully saturated yellow (light), and fully saturated blue and purple (dark) along the equator.
A color is fully specified by listing the three numbers for hue, value, and chroma in that order. For instance, a purple of medium lightness and fairly saturated would be 5P 5/10 with 5P meaning the color in the middle of the purple hue band, 5/ meaning medium value (lightness), and a chroma of 10 (see swatch). An achromatic color is specified by the syntax N V/. For example, a medium grey is specified by "N 5/".
In computer processing, the Munsell colors are converted to a set of "HVC" numbers. The V and C are the same as the normal chroma and value. The H (hue) number is converted by mapping the hue rings into numbers between 0 and 100, where both 0 and 100 correspond to 10RP.[7]
As the Munsell books, including the 1943 renotation, only contains colors for some points in the Munsell space, it is non-trivial to specify an arbitrary color in Munsell space. Interpolation must be used to assign meanings to non-book colors such as "2.8Y 6.95/2.3", followed by an inversion of the fitted Munsell-to-xyY transform. The ASTM has defined a method in 2008, but Centore 2012 is known to work better.[8]
Albert Munsell, an artist and professor of art at the Massachusetts Normal Art School (now Massachusetts College of Art and Design, or MassArt), wanted to create a "rational way to describe color" that would use decimal notation instead of color names (which he felt were "foolish" and "misleading"),[10] which he could use to teach his students about color. He first started work on the system in 1898 and published it in full form in A Color Notation in 1905.

A sample of companies that have hired our graduates include Apple, Dolby Laboratories, Google, Benjamin Moore, Canon Corp., Hallmark, Hewlett Packard Corp., Microsoft Corp., Pantone, Qualcomm Inc., Ricoh Innovations Inc., LG Electronics, and Samsung.
The Munsell Color Science Laboratory has a long history of supporting the greater color science community through dissemination of our research. This includes publications, software, imaging databases, measurements, and more. At a fundamental level, these pages represent much of what we've done over the last 35+ years of research activities.
The Munsell Color Company was founded by Professor Albert H. Munsell, the creator of the Munsell Color Order System and the Munsell Book of Color. The directors of the Munsell Color Company eventually sold the company's assets and created the Munsell Color Foundation. The Foundation was charged with furthering the scientific and practical advancement of color knowledge.
In 1983, the Foundation trustees voted to dissolve the foundation, and donate the proceeds to an academic institution for the creation and endowment of the Munsell Color Science Laboratory. RIT was selected as the recipient of this donation, and MCSL was born. (Note: There is no formal relationship between the RIT Munsell Color Science Laboratory and the commercial Munsell Color products sold by X-Rite.)
Initially, MCSL and the Color Science Department were part of RIT's College of Graphics Arts and Photography. RIT later created the Chester F. Carlson Center for Imaging Science, and MCSL became a research laboratory within that Center, currently housed in RIT's College of Science. In 1989, MCSL and the Center for Imaging Science moved to a new facility with approximately 6,500 square feet of space dedicated to color science research and education.
In the spring of 2003, space opened up in a nearby building. After extensive renovations, MCSL and the Color Science program moved into what is now formally called the Color Science Hall. The collocation of all our offices and laboratory space has fostered an amazing collaborative spirit in what was already an exciting, cooperative organization.
The Franc Grum Memorial Scholarship was established after his untimely death in 1985. It is intended to support scholarship in optical radiation measurements and color science. The funds for this award were made possible by gifts from the friends and family of Franc, as well as from industry. The scholarship is no longer presented as a separate award to individuals, but rather used to fund tuition for Color Science students in need.
Albert Munsell founded the Munsell Color Company in 1917. Later, in 1942, the Munsell Color Foundation was formed by the company to promote the advancement of the science of color. Ultimately, the Munsell Color Foundation led to the founding of this laboratory, the Munsell Color Science Laboratory, in 1983, at the Rochester Institute of Technology.
Unfortunately, no high-quality photo of Professor Munsell is available. In 1998, Munsell graduate student Doug Corbin restored the photo from Munsell's book, A Color Notation. The details of the procedure appeared in the February 1999 issue of Color Research and Application. Doug has provided the following information pertaining to this restoration:
Munsell Color Theory is based on a three-dimensional model in which each color is comprised of three attributes of hue (color itself), value (lightness/darkness) and chroma (color saturation or brilliance)
Munsell Color is comprised of the original Munsell Color Company that Albert H. Munsell started nearly a century ago. Our specialty is developing and producing physical color standards based on Munsell...
The Munsell Color order system is designed for the way you see and process color. That means you can literally take a color notation and visually imagine how it will look. After all, the developer of...
We got a chance to speak with Jennifer Cohlman Bracchi, Reference Librarian at Cooper Hewitt, Smithsonian Design Museum in New York City, to talk about a new color exhibit, Saturated: The Allure and Science of Color.
Planets in Star Wars films often challenge scientific standards of real life environments and their resulting soil surfaces. However, these intriguing lands, even if geologically odd, are truly fun to imagine and of course, to notate.
International Colour Day is March 21st, and to celebrate, Inter-Society Color Council (ISCC) is hosting a webinar with painter and teacher David Briggs, who will be presenting at the Munsell Centennial Color Symposium in June.
The Virtual Munsell Color Wheel is a simple online tool that lets you browse Munsell color notation in your web browser and obtain RGB and Hex values for chips. Detailed information about Munsell as a color space can be found elsewhere on the web (I recommend The Dimensions of Color, Handprint, and Munsell).
In the original version of the tool, I found some Munsell data online (from the Munsell Color Science Laboratory (MCSL) at Rochester Institute of Technology) that was already converted into sRGB and I just used that data.
For the last couple of days I have been amazed watching videos about the use of the Munsell book of Color championed by the UK artist Paul Foxton. Until then I thought that oil painting and still life artists were more focused on composition, concepts and values, instead of chroma, hue, and values. What he broadcasts makes a lot of sense, but he is very obsessed with the use of this system. I have purchased many videos in the last few months about still life and none of the artists mentioned the Munsell color system. I am trying to learn more about painting still life using oil.
Would someone make comments about it? Here is one of his videos.
