I didn’t realize LCH had an eye towards longevity with a splash of future-proofing in its color syntax. Now _that_ is something I can get excited about. One color syntax to rule them all! https://blog.jim-nielsen.com/2023/ok-lch-im-convinced/
@jimniels absolutely love OKLCH, just got done completely re-doing our color token system and used it to make all the color adjustments to keep perceptual hues the same across different shades and perceptual contrast the same across different colors. Super nice.
@jimniels here’s a bunch of the links I saved during my color research. I’m sure you’ve already come across some of them but figured I’d share in case some are useful

@danvpeterson ha wow, you went down the rabbit hole! I came across a couple of these, but most of them were new and they all look stellar. Appended them to my post with credit to you my friend. Thanks for passing them along! If you ever write something about this "color token system" work you did, hit me up with a link :)
@jimniels heh, yes, I definitely went *way* down the rabbit hole on this. Those are just the articles I saved, there were many more along with videos I should have bookmarked. Hoping to start actually blogging at some point this year to share some of this type of thing, have never actually done the blog thing before.
@jimniels APCA is super interesting as well if you haven’t already checked it out. Feels like the future and I’m looking forward to watching it progress as we move toward it for WCAG 3.
