colour.xyY_to_munsell_colour

colour.xyY_to_munsell_colour(xyY: Domain1, hue_decimals: int = 1, value_decimals: int = 1, chroma_decimals: int = 1) → str | NDArrayStr

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.

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
