Implementation of tetrahedral interpolation for color transformations.

Includes both the .blink file and also two expressions in a .nk file format. The second expression has controllable white and black corners in case needed. (example usage for that would be to remove certain colors in a subtractive color model fashion and then comp them back together)

My github repo where I will most likely be pushing any future updates: https://github.com/calvinsilly/Tetrahedral-Interpolation
