Rgb To Munsell Converter Weight

Free Excel file of 2352 Munsell colors with corresponding color values that you can search to find the nearest Munsell color and report it. A software conversion program available for reasonable $ where you can enter or cut-and-paste colorimetric values from EasyMatch QC and have the program report the corresponding Munsell color values. To convert from Munsell to sRGB, rst use the Munsell renotation to nd the corresponding CIE coordinates for that Munsell colour. Then use the sRGB standard to convert from those CIE coordinates to sRGB coordinates. Tables 1 through 41 show these results. When the cells in the table are shaded grey, clipping was needed to produce the sRGB triple.

The Virtual Munsell Color Wheel 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 The Dimensions of Color,Handprint, and Munsell).

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. 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 Munsell Color Science Laboratory’s 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 Ron Francis for their help during the development of this tool with testing and suggestions for improvement.

Color conversion based on a look-up table of common soil colors.

Arguments

the_hue

a vector of one or more more hues, upper-case (e.g. '10YR')

the_value

a vector of one or more values (e.g. '4')

the_chroma

a vector of one or more chromas (e.g. '6'), may be NA for neutral hues

alpha

numeric, transparency setting used when return_triplets = FALSE and returnLAB = FALSE

maxColorValue

maximum sRGB color value, typically 1 (see rgb)

return_triplets

logical, return sRGB coordinates (range 0-1) instead of standard hex notation of sRGB (e.g. '#8080B')

returnLAB

logical, return CIELAB coordinates (D65 illuminant)

Value

A vector of R colors is returned that is the same length as the input data. When return_triplets = TRUE and/or returnLAB = TRUE, then a data.frame (of sample length as input) is returned.

Details

This function is vectorized without recycling: i.e. the length of each argument must be the same. Both functions will pad output with NA if there are any NA present in the inputs.

Neutral hues are approximated by greyscale shades ranging from 20

Gley soil colors that are missing a chroma will not be correctly interpreted. Consider using a chroma of 1.Values of '2.5' (common in soil color descriptions) are silently truncated to '2'.Non-standard Munsell notation (e.g. '7.9YR 2.7/2.0') can be matched (nearest-neighbor, no interpolation) to the closest color within the munsell sRGB/CIELAB look-up table via getClosestMunsellChip(). A more accurate estimate of sRGB values from non-standard notation can be achieved with the munsellinterpol package.

Note

Rgb To Munsell Converter Weight Conversion

Care should be taken when using the resulting sRGB values; they are close to their Munsell counterparts, but will vary based on your monitor and ambient lighting conditions. Also, the value used for maxColorValue will affect the brightness of the colors. Th default value (1) will usually give acceptable results, but can be adjusted to force the colors closer to what the user thinks they should look like.
