3. History of Munsell Color Order System He created "rational way to describe color" that would use decimal notation instead of color names 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. Albert Munsell, an artist and professor of art at the Massachusetts Normal Art School

4. …History 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). Munsell was the first to separate hue, value, and Chroma into perceptually uniform and independent dimension He was the first to illustrate the colors systematically in three-dimensional space.

5. Introduction Munsell color order system: Munsell brought clarity to color communication by establishing an orderly system for accurately identifying every color that exists It defines colors by measured scales of hue, value, and Chroma, which correspond respectively to dominant wavelength, brightness, and strength or purity The system is also a color space for describing color of surfaces. It uses an irregular 3-dimensional color space. The dimensions are hue, value and Chroma

6. Munsell Color Attributes

7. …Attributes Munsell Hue Hue is that attribute of a color by which we distinguish red from green, blue from yellow… There is a natural order of hues: red, yellow, green, blue, purple. One can mix paints of adjacent colors in this series and obtain a continuous variation from one to the other.

8. …Hues Primary and Secondary Hue R,Y, G, B and P are called primary hues The intermediates between them namely YR, GY, BG, PB and RP five secondary hues Secondary are equidistant between the primaries.

9. …Attributes Munsell Value Value indicates the lightness of a color. The scale of value ranges from 0 for pure black to 10 for pure white via axis. The value scale applies to chromatic as well as neutral colors

10. …Attributes Munsell Chroma Chroma is the departure degree of a color from the neutral color of the same value Colors of low Chroma  are sometimes called “weak,” while those of high Chroma are said to be “strong ,” or “vivid

11. Color Description With Hue, Value and Chroma

12. Munsell Color Space and Solid Munsell color space Three-dimensional arrangement of colors with three attributes Munsell Color Solid All colors lie within a specific region of Munsell color space called the “Munsell color solid

13. Munsell Color Naming Munsell Color Naming Munsell has created a base-10 system for naming colors, using five primary hues and five secondary, or intermediates Subdividing each hue into 10 steps. 100 colors in total

14. Munsell Color Tree Three-dimensional representation of the Munsell system so called the Munsell color tree The vertical trunk of this Color Tree corresponds to the vertical value-scale axis of the sphere The branches extend outward horizontally from the trunk an each branch represents a series of increasing in Chroma ( constant HUE & VALUE ) HUES are spaced at equal intervals around the trunk

15. Munsell Color Notation It is representation of color with the three color attribute H V/C “ 10R” is the hue, meaning a red which leans toward orange rather than purple 7 is the value, which is two steps above middle gray 6 is the Chroma, which is relatively strong in nature.

16. How to Read Munsell Color Chart? The reading process involves two important steps Step 1: Understanding Color Attributes Hue is the color such as red, green, blue…. Value: is indicated with a number i.e. 2, 4, 6…The value scale runs vertically Chroma : Chroma is indicated with a number, typically in the range of 2-14. Its scale runs horizontally

17. …Reading Step 2 : Reading Color Notations Each color is designated with what is so far referred to as a color notation Notation : 5R 7/2 5R is the Hue 7 is the Value 2 is the Chroma These colors can then be referenced on a Munsell color chart to see what the notation looks like.

18. Munsell Color System Standards and Their Application Popular applications for Munsell color standards : Designers and brand owners use them to visually communicate color to suppliers Munsell government standards help the U.S. Department of Agriculture grade and timely harvest produce Munsell environmental color communication standards have been specially developed to help archeologists, botanists, geologists and scientists reveal clues about our environment

19. Application Areas of Munsell Color Order System Munsell color order system is used in: A soil scientist accurately assessing the makeup of the soil in the field An artist in the studio replicating colors when mixing paints or materials Quality control experts making sure final product colors match the set standard. Electricians staying safe using standard color codes A food scientist using custom colors to bring consistent and reliable results

20. Advantage of the Color Order System from Munsell Some Advantages Loose and unrelated color terms are replaced by a definite notation New colors in no way disturb the orderly classification as a place is already awaiting them. Color may be easily and rapidly specified by direct perceptual comparison Color communication made easy! Satisfies the legal community Easily used directly in the field !

21. Limitations of the system Practical disadvantages of M unsell color system: Colors are defined only for a two-degree observer and a C illuminant No analytical expressions to convert the CIE system to the Munsell system, or vice versa, exist
