polarLUV: Create polarLUV Colors

Description

This function creates colors of class ``polarLUV''; a subclass of the virtual ``color'' class.

Usage

polarLUV(L, C, H, names)

Arguments

L,C,H
these arguments give the L, C and H coordinates of the colors. The values can be provided in separate L, C and H vectors or in a three-column matrix passed as L.
names
A vector of names for the colors (by default the row names of L are used).

Value

  • An object of class ``polarLUV'' which inherits from class ``color.''

Details

The polarLUV space is a transformation of the CIE $L^*u^*u^*$ space so that the $u$ and $u$ values are converted to polar coordinates. The radial component $C$ measures chroma and the angular coordinate $H$ is measures hue.
