colour.xyY_to_munsell_colour#

colour.xyY_to_munsell_colour(xyY: Domain1, hue_decimals: int = 1, value_decimals: int = 1, chroma_decimals: int = 1, method: Literal['Centore 2014', 'ONNX'] | str = 'Centore 2014') → str | NDArrayStr[source]#

Convert from CIE xyY colourspace to Munsell colour notation.

Parameters:

xyY (Domain1) – CIE xyY colourspace array representing chromaticity coordinates and luminance.
hue_decimals (int) – Number of decimal places for formatting the hue component.
value_decimals (int) – Number of decimal places for formatting the value component.
chroma_decimals (int) – Number of decimal places for formatting the chroma component.
method (Literal['Centore 2014', 'ONNX'] | str) – Computation method.

Returns:

Munsell colour notation formatted as “H V/C” where H is hue, V is value, and C is chroma.

Return type:

str or numpy.NDArrayFloat
