luvtoMunsell: Convert CIE Luv coordinates into a Munsell specification

Description

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

Usage

luvtoMunsell( Luv, white=c(95.047,100,108.883), adaption='bradford', ... )

Arguments

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

adaption

method for chromatic adaption, see Details

...

other parameters passed to XYZtoMunsell()

Value

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

Details

The conversion is done in 3 steps.

• Luv XYZ using luv2xyz() with the given white.

• XYZ is then adapted from the given white to Illuminant C using the given adaption method, see adaption.

• XYZ HVC using XYZtoMunsell()
