XYZ was designed (by the use of super-saturated, not physically realizable) to use positive numbers only. However, negative numbers do crop up as a result of chromatic adaptation and this is the case here: Lab uses D50 and Oklab uses D65. > Should the LMS logic clamp channels so that they're 0 at minimum? In general we want to avoid clamping intermediate results. > Should it take the cube root of the absolute value and then match the sign afterwards? That seems a reasonable way to handle it (and is what is done for the extended transfer functions for RGB color spaces). -- GitHub Notification of comment by svgeesus Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/9477#issuecomment-1766777524 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
