Color transformations using tetrahedral interpolation, includes both an implemention for the expression node and blinkscript.
For folks unfamiliar with Steve Yedlin, ASC: These implementations are supposed to be replications of the one's Yedlin showcasesd. A video where he willingly showed half of the blinkscript code can be found in the end of this page below (0:14:30). Where I only attemped to reconstruct the missing parts with the help of some math from various papers also linked in the end of the page below, which I then later also translated to the expression node for NC Nuke users.
TetraAutomater is only the suggestion of what it could be doing, since it was never mentioned.
I just want to be able to share these for everyone to use. So I don't expect any credit from it!

As the name suggests, matches the 6 colors automatically, given an input and output. Can also be used for an inverse operation but not recommended.
Originally written for MATLAB by Juanjo Salazar, solution was later translated to python by Ethan Ou and now an explicit algebraic solution was found using Mathematica, which avoids the use of python and for solving the same system of equations everytime.
