⚠️There's a newer version (3.1-0) of this package.Take me there.

munsellinterpol (version 1.0.2)

Interpolate Munsell Renotation Data from Hue/Chroma to CIE/sRGB

Description

Methods for interpolating data in the Munsell color system following the ASTM D-1535 standard. Hues and chromas with decimal values can be interpolated and converted to/from the Munsell color system and CIE xyY, CIE XYZ, sRGB, CIE Lab or CIE Luv. Chromas can be odd and hue steps can be real numbers. Based on the work by Paul Centore, "The Munsell and Kubelka-Munk Toolbox".
