“I have designed a new perceptual colour space, designed to be simple to use, while doing a good job at predicting perceived lightness, chroma and hue. It is called the Oklab colour space, because it is an OK Lab colour space.” — https://bottosson.github.io/posts/oklab/
A colour in Oklab is represented with three coordinates, similar to how CIELAB works, but with better perceptual properties. Oklab uses a D65 whitepoint, since this is what sRGB and other common colour spaces use.

The only thing that you need to understand is that OKLAB gradients are much more perceptually correct than HSL. - https://www.youtube.com/watch?v=fv-wlo8yVhk&ab_channel=Acerola
