===Reverse transformation===The reverse transformation is most easily expressed using the inverse of the function "f" above::formula_5where:formula_6==Hunter Lab==L is a correlate of lightness, and is computed from the "Y" tristimulus value using Priest's approximation to Munsell value:: formula_7where "Y""n" is the "Y" tristimulus value of a specified white object.
The transformation from CIELUV to XYZ is performed as following:: formula_58: formula_59: formula_60: formula_61: formula_62== Hunter Lab Color Space ==L is a correlate of Lightness, and is computed from the Y tristimulus value using Priest’s Approximation to Munsell Value:formula_63where Yn is the Y tristimulus value of a specified white object.
