The is a simple online tool that lets you browse the Munsell color notation in your web browser. Detailed information about Munsell as a color space can be found elsewhere on the web (I recommend and ).At the bottom of this tool you will see a circle of hue squares. Click on a square to choose that hue page; the upper portion of the screen will change to show you a “hue page” showing your selected hue at various values and chromas.Within the hue page at the top of the screen, hover your mouse over any square to see the Munsell notation for that square: Hue Value/Chroma.

The conversion of Munsell soil colors to RGB triplets, suitable for displaying on a computer screen or printing, is made complicated by the numerous operations involved in converting between color spaces. Figure 1 shows all possible (both real and unreal) Munsell color chips in the L.U.V color space. Rgb to munsell converter money It may also be possible to simulate orto movies if you like it can give the computer can also make other.

If you click on the square, the box at the lower right will display the color you selected in 3 formats: Munsell notation, RGB decimal, and RGB hexadecimal. You can select/copy/paste these values into your favorite design tool (e.g., the Photoshop color chooser).This is version 0.5 of the Virtual Munsell Color Wheel. Color data for this tool was taken from the web page, which lists RGB values for those chips which are within the gamut of the sRGB color space. Thus, the colors you see here are only those that can be displayed relatively accurately on a calibrated monitor and will differ from those found in printed Munsell books.Many thanks to Glenn Tait and for their help during the development of this tool with testing and suggestions for improvement.
The Munsell color system was designed as a series of discrete color chips which closely approximation to the color sensitivity of the human eye. The description of color via three variables tied to perceptible properties (hue, value, and chroma) under a standardized illuminant (sunlight on a clear day) makes the Munsell system a good choice for recording and interpreting soil color data.

However, numerical analysis of colors encoded in the Munsell system is difficult because they are from a discrete set of color chips and referenced by values that include both letters and numbers. (2006) give a good background on various color space models and their relative usefulness in the realm of soil science.
The conversion of Munsell soil colors to RGB triplets, suitable for displaying on a computer screen or printing, is made complicated by the numerous operations involved in converting between color spaces. Figure 1 shows all possible (both real and unreal) Munsell color chips in the L.U.V color space. Figure 2 shows some of the common soil color chips in the same color space. Figures 2 through 5 depict common soil colors in the RGB color space, visualized both in R and POVRAY.
