LuvtoMunsell

Convert CIE Luv coordinates into a Munsell specification

LuvtoMunsell Converts CIE Luv coordinates into a Munsell specification, by interpolating over the extrapolated Munsell renotation data

LuvtoMunsell( Luv, white=c(95.047,100,108.883), adapt='Bradford', ... )

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

The conversion is done in 3 steps.

Luv → XYZ using XYZfromLuv() with the given white.
XYZ is then adapted from the given white to Illuminant C using the given chromatic adaptation method, see CAT().
XYZ → HVC using XYZtoMunsell()

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