luminance2munsell

luminance2munsell#

stimupy.utils.luminance2munsell(lum_values, reference_white)#

Transform luminance values into Munsell values. The luminance values do not have to correspond to specific units, as long as they are in the same unit as the reference white, because Munsell values are a perceptually uniform scale of relative luminances.

Parameters:

  • lum_values (numpy-array)

  • reference_white (number)

Returns:

  • munsell_values (numpy-array)

  • Reference (H. Pauli, “Proposed extension of the CIE recommendation)

  • on ‘Uniform color spaces, color difference equations, and metric color

  • terms’,” J. Opt. Soc. Am. 66, 866-867 (1976)
