.. py:function:: stimupy.utils.munsell2luminance(munsell_values, reference_white)


   Transform Munsell values to luminance values.
   The luminance values will be in the same unit as the reference white, which
   can be arbitrary as long as the scale is linear.

   :param munsell_values:
   :type munsell_values: numpy-array
