Methods of representing color include RGB, hexadecimal notation and the Munsell Color System, invented by American art educator Albert Munsell. The “munsell” package is an easy-to-use package for working with the Munsell color system and Munsell color charts, and for creating isochromatic surfaces.
The Munsell color system is based on 10 hues, which are further divided into 10 categories of 100 hues, with 10 categories of lightness and three attributes of saturation. Colors are described as ‘hue lightness/saturation’.
・10 categories of lightness
R(red), YR(yellow-red), Y(yellow), GY(green-yellow), G(green), BG(blue-green), B(blue), PB(purple-blue), P(purple-purple), RP(red-violet)
The Munsell color system is a little difficult to understand, but checking the isochromatic areas will help you understand it better.
Package version is 0.5.0. Checked with R version 4.2.2.
Run the following command.
#Install Package install.packages("munsell")
See the command and package help for details.

I hope this makes your analysis a little easier !!
