XYZ {colorspace} | R Documentation |
This function creates colors of class XYZ; a subclass of the virtual ``color'' class.
XYZ(X, Y, Z, names)
X,Y,Z |
these arguments give the X, Y and Z coordinates of
the colors. The values can be provided in separate X ,
Y and Z vectors or in a three-column matrix
passed as X . |
names |
A vector of names for the colors (by default the row
names of X are used). |
The X, Y and Z values are the levels of the CIE primaries. These are scaled so that the luminance of the display white-point is 100. The white-point is taken to be D65, which means that its coordinates are 95.047, 100.000, 108.883.
An object of class ``XYZ'' which inherits from class ``color.''
