Hi, some version of this commit would be good to merge. However, Gifsicle already has multiple color-distance algorithms, including one used by @kornelski’s --lossy option, and the kcolor subsystem used by quantize.c. It seems weird to add another, especially since I’d love to rewrite the existing quantize.c subsystem to optionally use the Oklab color space.

[kohler]

So if you could change this commit to use the kcolor framework that would be great.

Thanks for your response! Sure, we added this to our backlog and we will work on that soon.
