Thanks a lot for this, I was hoping to learn with this blog post. Correctness is the highest priority for me, so I'm glad to improve my library.

I will update the library to use 16-bit color everywhere (0-65535), and update the blog post to note this.

As for the rounding, that's another great point, and thanks for the link. I will change the library and blog post to round to the even number on ties.

Edit: I've updated the blog post, I'd appreciate if you could check it out and let me know if I made any mistakes with the update.
