Illuminants Chromaticity Coordinates

Defines CIE illuminants chromaticity coordinates for the CIE 1931 2 Degree Standard Observer and CIE 1964 10 Degree Standard Observer.

The following CIE illuminants are available:

• CIE Standard Illuminant A
• CIE Illuminant B
• CIE Illuminant C
• CIE Illuminant D Series (D50, D55, D60, D65, D75)
• CIE Illuminant E
• Illuminants F Series (F1, F10, F11, F12, F2, F3, F4, F5, F6, F7, F8, F9, FL3.1, FL3.10, FL3.11, FL3.12, FL3.13, FL3.14, FL3.15, FL3.2, FL3.3, FL3.4, FL3.5, FL3.6, FL3.7, FL3.8, FL3.9)
• High Pressure Discharge Lamps (HP1, HP2, HP3, HP4, HP5)

The following other illuminants are available:

• DCI-P3 (CIE 1931 2 Degree Standard Observer only) [2]

Illuminants IPython Notebook

Warning

DCI-P3 illuminant has no associated spectral power distribution. DCI has no official reference spectral measurement for this whitepoint. The closest matching spectral power distribution is Kinoton 75P projector.

Notes

• CIE illuminants with chromaticity coordinates not defined in the reference [1] have been calculated using their relative spectral power distributions and the colour.colorimetry.tristimulus.spectral_to_XYZ() definition.
