oklab() and oklch() are okay versions of lab() and lch() because lab() and lch() are not okay.
I will not pretend that I really understand this whole color on the web thing, how it works or why one color function offers many more options to developers than the other, but I did learn several things during this experiment. I understand why a color function like hsl() offers better DX than rgb(). I’ve learned that rgb(), hsl(), and hwb() use colors from the sRGB color space, and lab() and lch() colors from the CIELAB color space. These color functions are relevant now because they support more colors and modern monitors can display them. It kinda also makes sense to me why some people say that using lch() is more intuitive than lab().
This doesn’t sound too bad, but as soon as I dig deeper into colors, I soon reach a point where I’m out. It’s usually a graph or complicated formula that stops my enthusiasm. Why am I saying this? I don’t know, maybe self-defense, maybe to make you feel better and assure you it’s fine to not understand everything.
Anyway, now I’ve added hsl(), hwb(), lab(), and lch() to my tool belt, and along comes mary oklab() and oklch(). lab and lch are great, but not perfect. The main issue with lab and lch is that there's a bug with blue colors which turns blue purple.
oklab() and oklch() fix that.
The okay versions of lab and lch come with additional improvements. You can learn more about it Chris Lilley's presentation “Better than Lab? Gamut reduction CIE Lab & OKLab”.
