I think we all agree that Lab interpolation is in every way superior, and the only reason we can't switch everything to that by default is backwards compat, right? Assuming the above statement is correct, I think anything where authors have to explicitly enable lab interpolation is a bad idea from a usability point of view and should be a last resort if nothing more reasonable can be implemented. It seems reasonable to me that as long as there's at least 1 non-sRGB color, the interpolation should happen in Lab, since there's no backwards compat concern. > If a gradient/animation uses a mixture of lab() and rgb() colors, I assume it would fall back to RGB interpolation. If you interpolate Lab and sRGB via sRGB interpolation, you could end up having an abrupt jump in the first interpolation step, since the Lab color may be outside the sRGB gamut. Given that sRGB is rather small compared to Lab, that's not a rare case, but significantly more than 50% likely. Interpolation must always happen in a superset of the gamuts of the colors involved, so Lab is a safe choice, whereas sRGB is not. > What happens if you mix lab() and colors in one of the other predefined colorspaces (display-p3, rec-2020 etc)? Given that Lab encompasses all visible colors, Lab interpolation should be safe here too. -- GitHub Notification of comment by LeaVerou Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/4647#issuecomment-571146241 using your GitHub account
