colour.temperature.CCT_to_xy_CIE_D¶

colour.temperature.CCT_to_xy_CIE_D(CCT: FloatingOrArrayLike) → numpy.ndarray[source]¶

Return the CIE xy chromaticity coordinates of a CIE Illuminant D Series from its correlated colour temperature \(T_{cp}\).

Parameters: CCT (FloatingOrArrayLike) – Correlated colour temperature \(T_{cp}\).
Returns: CIE xy chromaticity coordinates.
Return type: numpy.ndarray
Raises: ValueError – If the correlated colour temperature is not in appropriate domain.
