RE: is any WCAG criteria to account both default and Dark mode for content

WCAG does not have any requirements relating to dark mode. It requires that authors publish web content that meets the success criteria. The author has no responsibility if users apply alternative colour themes.

That’s not to say that it’s not an accessibility consideration or that authors should not take measures to accommodate alternative colour themes. It’s just not a WCAG requirement.

Hi!
I am looking for clarification on if any WCAG requirement if users switch to dark mode on mobile devices.

for emails, you know how mobile can switch to dark mode.
sometimes code doesn't account for the dark mode and now there are color contrast issues with the text
is there currently a WCAG requirement for emails to ensure that they're coded to swap colors for dark mode?

Please suggest. appreciated your guidance on this.
Have a good weekend all.


Thanks!
~ Kiran
