WhitePoint

is an option for ColorConvert, ChromaticityPlot and other functions to specify the white point.

Details

  • WhitePoint, also known as the reference white, defines the white color for a specific color space.
  • Typical settings include:
  • Automaticautomatically determine the white point to use
    "name"use a named white point
    coluse the color col as white point
  • Common named white points include:
