You want the image to reflect the correct mode no matter what page it is shown on. Yes I think that's a more difficult problem because the HTML parser immediately fetches any img or video sources it finds. It wouldn't be able to evaluate the _used colour scheme_ when initially parsing the HTML. But maybe it could be done when in combination with `<img loading=lazy>`. I think it's a problem that needs to be discussed in the WHATWG. -- GitHub Notification of comment by JoshTumath Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/10249#issuecomment-3779706575 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
