LabtoMunsell

Convert CIE Lab coordinates into a Munsell specification

LabtoMunsell Converts CIE Lab coordinates to a Munsell specification, by interpolating over the extrapolated Munsell renotation data

LabtoMunsell( Lab, white=c(95.047,100,108.883), adapt='Bradford', ... )

`Lab`	CIE Lab coordinates An Nx3 matrix, or a vector that can be converted to such a matrix. Each row of the matrix has Lab.
`white`	XYZ for the source white. The default is Illuminant=D65, 2 observer
`adapt`	method for chromatic adaptation, see `CAT()` for valid values. Also see Details.
`...`	other parameters passed to `XYZtoMunsell()`

The conversion is done in 3 steps.

Lab → XYZ using XYZfromLab() with the given white.
XYZ is then adapted from the given white to Illuminant C using the given adapt method.
XYZ → HVC using XYZtoMunsell().

An Nx3 matrix with the Munsell HVC coordinates in each row. The rownames are set to those of Lab.
