> ....compositing should be done in a linear-light space like CIE Lab.... I do agree that *most* compositing is *usually* best in a linearized space. BUT..... LAB is not a linear light space, and I know you know LAB and LUV are perceptual, so not sure which space was actually meant? In Film/TV **LUV** or a variant is commonly used, at least "in the guts" of color grading gear. **LAB** is better suited to reflected colors. I don't remember any time where I used either for compositing though, only for adjusting/grading. In film/TV typically we linearize RGB. In particular, when possible we linearize the destination or delivery workspace, then the only transform needed on output is applying the transfer curve. Here's a GIST comparing LAB and LUV: [**Where's the LUV?**](https://gist.github.com/Myndex/47c793f8a054041bd2b52caa7ad5271c) -- GitHub Notification of comment by Myndex Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/5883#issuecomment-787856520 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
