dd8 has just created a new issue for https://github.com/w3c/csswg-drafts: == [css-color-4] statement about range of 'a' parameter in lab() appears incorrect == The spec says > The second and third arguments are the distances along the "a" and "b" axes in the Lab color space, as described in the previous section. These values are signed (allow both positive and negative values) and theoretically unbounded (**but in practice do not exceed ±160**). https://drafts.csswg.org/css-color-4/#specifying-lab-lch However, there are several files in the WPT test suite where the "a" parameter exceeds the ±160 range: - https://wpt.live/css/css-color/prophoto-rgb-004-ref.html lab(87.5745% -186.6921 150.9905); - https://wpt.live/css/css-color/prophoto-rgb-004.html lab(87.5745% -186.6921 150.9905); - https://wpt.live/css/css-color/rec2020-004-ref.html lab(85.7729% -160.7259 109.2319); - https://wpt.live/css/css-color/rec2020-004.html lab(85.7729% -160.7259 109.2319); - https://wpt.live/css/css-color/xyz-004-ref.html lab(99.6289% -354.58 146.707); - https://wpt.live/css/css-color/xyz-004.html lab(99.6289% -354.58 146.707); - https://wpt.live/css/css-color/xyz-d65-004-ref.html lab(99.6289% -354.58 146.707); - https://wpt.live/css/css-color/xyz-d65-004.html lab(99.6289% -354.58 146.707); Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/12208 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
