R: Create XYZ Colors

XYZ {colorspace} | R Documentation

## Create XYZ Colors

### Description

This function creates colors of class XYZ; a subclass of the virtual `color-class` class.

### Usage

    XYZ(X, Y, Z, names)

### Arguments

`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).

### Details

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.

### Value

An object of class `XYZ` which inherits from class `color`.
