-       CIE 15:2004 CIELab is defined as:
-
-       L* = 116*f(Y/Yn) - 16                     0 <= L* <= 100
-       a* = 500*[f(X/Xn) - f(Y/Yn)]
-       b* = 200*[f(Y/Yn) - f(Z/Zn)]
-
-       and
-
-              f(t) = t^(1/3)                     1 >= t >  (24/116)^3
-                     (841/108)*t + (16/116)      0 <= t <= (24/116)^3
-
-
-       Reverse transform is:
-
-       X = Xn*[a* / 500 + (L* + 16) / 116] ^ 3   if (X/Xn) > (24/116)
