For RGB to Munsell conversion, a dataframe (NA-padded) of hue, value, chroma, and Euclidean distance to nearest matching color is returned. 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).
To use the Munsell Calculator, go to Hue 1 - select the appropriate button. Then enter the Hue 2, Value, and Chroma values. The Munsell code will appear in the Code/Color row, along with the soil color name and a color strip. To use a second color to describe the soil color, press the “+” button after entering the code for the first color. For Munsell to RGB conversion, a vector of R colors is returned that is the same length as the input data. If returntriplets is TRUE, then a dataframe (of sample length as input) of r,g,b values is returned. For RGB to Munsell conversion, a dataframe (NA-padded) of hue, value, chroma, and Euclidean distance to nearest matching color is.
Description
RGBtoMunsell Converts RGB coordinates to a Munsell specification, by interpolating over the extrapolated Munsell renotation data
Usage
Arguments
RGB | a numeric Nx3 matrix with RGB coordinates in the rows,or a vector that can be converted to such a matrix, by row.These are non-linear display values, but they are not required to be integers. |
space | the name of an installed RGB space.Spaces |
maxSignal | maximum value of RGB for display.Other popular values are 1, 1023, and 65535.Even when 1, they are still taken to be non-linear display values. |
adapt | method for chromatic adaptation,see |
... | other parameters passed to |
