colour.colorimetry.sds_and_msds_to_sds(sds: Sequence[SpectralDistribution | MultiSpectralDistributions] | SpectralDistribution | MultiSpectralDistributions | ValuesView) → List[SpectralDistribution]

Convert given spectral and multi-spectral distributions to a list of spectral distributions.

Parameters:

sds (Sequence[SpectralDistribution | MultiSpectralDistributions] | SpectralDistribution | MultiSpectralDistributions | ValuesView) – Spectral and multi-spectral distributions to convert to a list of spectral distributions.

Returns:

List of spectral distributions.

Return type:

list
