With this script I calculate the delta e between each color. It works fine, but it's a lot of work when I have to add another color. So my question is: is there a function to compare each color with eachother at the same time?

  • I think you are asking: how to get all possible pair permutation from elements in one set? [Then it will be trivial to calculate the deltaE] -- so, something like https://stackoverflow.com/questions/14169122/generating-all-unique-pair-permutations? – Giacomo Catenazzi Jul 08 '21 at 14:21
  • Yes it is somthing like that, but how can I implement this in my script? – Thijs Brokking Jul 08 '21 at 14:54
