LUV.Rd
This function creates colors of class ``LUV''; a subclass of the virtual
colorclass
class.
LUV(L, U, V, names)
L, U, V  these arguments give the L, U and V coordinates of the colors.
The values can be provided in separate 

names  a vector of names for the colors (by default the row names of

An object of class LUV
which inherits from class color
.
The L
, U
and V
values give the coordinates of the
colors in the CIE (1976) \(L^*u^*v^*\) space. This is a
transformation of the 1931 CIE XYZ space which attempts to produce
perceptually based axes. Luminance takes values between 0 and 100, and the
other coordinates take values between 100 and 100. The \(a\) and \(b\)
coordinates measure positions on green/red and blue/yellow axes.
