 The derivatives of $R$ have already been computed in the previous step. Doing this step by step will eventually lead to $(dif (Delta E)) / (dif L^*)$,  $(dif (Delta E)) / (dif a^*)$ and $(dif (Delta E)) / (dif b^*)$ and ultimately the gradient of $Delta E$. Take a look at the #link("https://github.com/enneract/colour/blob/b8c113efb7b819fce81213e6f6fa41db90b0b61c/colour/recovery/jakob2019.py#L198-L252")[full code] to see all the formulas.

 There is a clever trick to "automagically" compute derivatives, without having to go step-by-step, differentiating every operation and writing code manually like I did. #link("https://en.wikipedia.org/wiki/Dual_number")[Dual numbers] have the interesting property that, when used correctly, their dual parts are the derivatives of their real parts. They're defined very similarly to complex numbers, but instead of $z = a + b i$, $i^2 = -1$, one has $z = a + b epsilon$, $epsilon^2 = 0$. (Even more interestingly, this can be extended to higher derivatives as well!). See #link("https://en.wikipedia.org/wiki/Automatic_differentiation")[automatic differentiation] on Wikipedia.
