soil_color

The function converts the visible soil spectrum to three-dimensional color systems, such as Munsell and RGB, using the CIE tristimulus values for the conversion. This allows for the standardized representation of colors and facilitates visual and comparative analysis.

Calculate the ratio of iron oxides, hematite and goethite, in
soil using the diffuse reflectance technique. The Kubelka-Munk theory,
second derivative analysis, and spectral region amplitudes related to
hematite and goethite content are used for quantification (Torrent,
J., & Barron, V. (2008) <doi:10.2136/sssabookser5.5.c13>).
Additionally, the package calculates soil color in the visible
spectrum using Munsell and RGB color spaces, based on color theory
(Viscarra et al. (2006) <doi:10.1016/j.geoderma.2005.07.017>).
