colour.sd_CIE_standard_illuminant_A#
- colour.sd_CIE_standard_illuminant_A(shape: SpectralShape = SPECTRAL_SHAPE_DEFAULT) SpectralDistribution [source]#
CIE Standard Illuminant A is intended to represent typical, domestic, tungsten-filament lighting.
Its spectral distribution is that of a Planckian radiator at a temperature of approximately 2856 K. CIE Standard Illuminant A should be used in all applications of colorimetry involving the use of incandescent lighting, unless there are specific reasons for using a different illuminant.
- Parameters:
shape (SpectralShape) – Spectral shape used to create the spectral distribution of the CIE Standard Illuminant A.
- Returns:
CIE Standard Illuminant A. spectral distribution.
- Return type:
