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

L, C, H |
these arguments give the L, C and H coordinates of the colors.
The values can be provided in separate |

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.
An object of class polarLUV which inherits from class color.
