Maybe it will help if I illustrate my confusion. Consider Lab which has a reference range of 125 and -125. In Lab the threshold would be (125 - -125) / 100,000 = 0.0025. I assume then the a and b component are compared to this threshold, so `lab(50% 0.0025 0.0025)` is on the edge of this threshold. The reference range for LCh is 150 for chroma, 150 / 100,000 = 0.0015. If we convert `lab(50% 0.0025 0.0025)` to LCh, we get `lch(50% 0.00354 45)` which exceeds the achromatic threshold in LCh. Is that desired? Do we care that LCh and Lab, which represent the same space, but in different coordinates, have a difference in what they consider achromatic? -- GitHub Notification of comment by facelessuser Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/11706#issuecomment-2758855152 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
