CCT_to_uv_Ohno2013
(CCT, D_uv=0, cmfs=XYZ_ColourMatchingFunctions(name='CIE 1931 2 Degree Standard Observer', ...))[source]¶ Returns the CIE UCS colourspace uv chromaticity coordinates from given correlated colour temperature \(T_{cp}\), \(\Delta_{uv}\) and colour matching functions using Ohno (2013) method.
Parameters: - CCT (numeric) – Correlated colour temperature \(T_{cp}\).
- D_uv (numeric, optional) – \(\Delta_{uv}\).
- cmfs (XYZ_ColourMatchingFunctions, optional) – Standard observer colour matching functions.
Returns: CIE UCS colourspace uv chromaticity coordinates.
Return type: ndarray
