Is there a way to scale the Lightness in OKLab/OKLCH color space, so it becomes identical to lightness in CIELAB? I want use OKLab to create tonal palettes, that requires a change in lightness scale since OKLab’s lightness scale perfoms poorly in this regard.
This is an extremely complex topic, you’re unlikely to find any experts on it unfortunately.
My best (still bad) suggestion would be to temporarily switch color spaces and remap the colors on the fly.
