We're probably in general agreement, but.... On Mar 8, 2021, at 5:06 PM, Patrick H.

Contrast checks are done against what the author defined, not against what the end result of a user adaptation may be, though ... because authors cannot account for the quirks in which users may have set their particular environment, what non-standard changes a particular OS/user agent does when switching to some form of forced dark or high contrast mode, etc. In this case, I would argue that the author did not fully define the color palette to ensure contrast across multiple platforms. There's a different between specifying black text on white and black text on "default". The former is less likely to fail in dark mode (and I do know this from experience...) If a user chooses to always override the author, then it's a different situation. I'm interpreting your comments that the burden of remediating a darkmode glitch would fall on the user, but if the darkmode user is using it reduce visual strain, then it could be considered an accessibility issue to the user. The ideal is to NOT have the user remediate bad content. Not saying anything about the burden, and yes an author should test and make sure their output is resilient. Again, we're making the distinction that this is NOT about WCAG compliance (which is silent about dark mode etc at this point), and goes beyond the normative requirements of WCAG. Just want to be clear that if something fails to correctly adapt to dark mode, we can't just go around saying "so this fails WCAG". This is where I think it's sometimes important to go beyond strict WCAG compliance, especially with new technologies. There will always be a gap in emerging technologies and the exact standard. It seemed like people were saying that if it's not in WCAG, it isn't something to worry about. I don't think you agree with that. For these reasons, I personally would recommend testing your email messages on darkmode. As I said, I've seen many colleagues switching to that mode. And that's good advice of course. Just being clear that this goes beyond the pure requirements of WCAG. Duly noted... P Elizabeth =-=-=-=-=-=-=-=-=-=-=-=-= Elizabeth J.
