Can you talk a bit more on what makes this hard from your experience/pov, asking as someone who doesn't have much experience with this type of work

Agreed - I remember implementing colour quantisation in MATLAB at university and it seemed simple enough, though we only used it for some simple cases (to learn the theory more than anything). Looking at some of the example images there it looks like it's easy to hit edge cases.
