polarLUV

Create polarLUV (HCL) Colors

Description

This function creates colors of class “polarLUV”; a subclass of the virtual color-class 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).

Details

The polarLUV space is a transformation of the CIE L*u*v* space so that the u and v values are converted to polar coordinates. The radial component C measures chroma and the angular coordinate H is measures hue. It is also known as the HCL (hue-chroma-luminance) space.

Value

An object of class polarLUV which inherits from class color.
