Does this apply to LCh as well? Is LCh using `c / 100,000` and Lab using `(a - b) / 100,000` or does LCh need to break chroma into a and b values so it can have a similar threshold to it's rectangular counter part? I bring this up because chroma divided by 100,000 and the difference of a and b divided by 100,000 will produce different thresholds, but Lab and LCh are the same color spaces, just represented in different coordinate systems. I assume the desire is that the achromatic threshold would be the same for both rectangular and polar representations. It seems you could provide interlock between the two coordinate systems by either selecting the difference of a and b divided by 100,000, converting polar chroma to a - b, or by specifying the reference range as chroma divided by 100,000 and requiring Lab-like representations to convert a and b to chroma when checking. -- GitHub Notification of comment by facelessuser Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/11706#issuecomment-2758443926 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
