RGB_2_degree_cmfs_to_XYZ_2_degree_cmfs
(wavelength)[source]¶ Converts Wright & Guild 1931 2 Degree RGB CMFs colour matching functions into the CIE 1931 2 Degree Standard Observer colour matching functions.
Parameters: wavelength (numeric or array_like) – Wavelength \(\lambda\) in nm. Returns: CIE 1931 2 Degree Standard Observer spectral tristimulus values. Return type: ndarray Notes
- Data for the CIE 1931 2 Degree Standard Observer already exists, this definition is intended for educational purpose.
