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:
  • Automatic automatically determine the white point to use
    "name" use a named white point
    col use the color col as white point
  • Common named white points include:
  • "A" - XYZColor [1.098466069456375`,1,0.3558228003436005`]
    "B" - XYZColor [0.9909274480248003`,1,0.8531327322886154`]
    "C" - XYZColor [0.980705971659919`,1,1.1822494939271255`]
    "D50" - XYZColor [0.9642119944211994`,1,0.8251882845188288`]

  • The sRGB color space is defined with "D65", and the XYZ color space is usually defined with "D50".

Examples

Basic Examples  (2)

Convert a white sRGB color using the default white point:

Wolfram Language code: ColorConvert[RGBColor[1, 1, 1], "XYZ"]//InputForm

Use a custom white point:

Wolfram Language code: ColorConvert[RGBColor[1, 1, 1], "XYZ", WhitePoint -> "D65"]//InputForm

Show a white point on a slice of the sRGB space:

Wolfram Language code: ChromaticityPlot["sRGB", WhitePoint -> Automatic]

Turn the white point off:

Wolfram Language code: ChromaticityPlot["sRGB", WhitePoint -> None]

Scope  (4)

Color Conversion  (1)

Convert from XYZ to Lab using the default white reference (D50):

Wolfram Language code: ColorConvert[XYZColor[.3, .4, .5], "LAB"]//InputForm

Specify a different white:

Wolfram Language code: ColorConvert[XYZColor[.3, .4, .5], "LAB", WhitePoint -> "D65"]//InputForm

Visualization  (3)

Show a particular white point:

Wolfram Language code: ChromaticityPlot["RGB", WhitePoint -> "E"]

Choose a specific color as the white point:

Wolfram Language code: ChromaticityPlot["RGB", WhitePoint -> XYZColor[.9, 1, .8]]

Specify a list of white points:

Wolfram Language code: ChromaticityPlot["RGB", WhitePoint -> {"D50", "D65"}]

Applications  (1)

Compare the RGB gamut with the complete series of supported fluorescent white points:

Wolfram Language code: ChromaticityPlot3D["RGB", "XYZ", WhitePoint -> ("F" <> ToString[#]&) /@ Range[12]]
