RE: Dark Mode best Practise

If your only concern is WCAG compliance, it's not at all obvious to me that you need to test Dark Mode at all. If the default display theme is WCAG compliant, it's not the author's problem if users select alternate themes or other customisations that are inaccessible. They have always been able to do that.

If you are concerned about the user experience rather than WCAG, then you need to test all the things you mentioned. However, according to the Apple documentation it looks like it will be a massive pain to specify alternate colours for dark mode - it looks like days or weeks of work rather than minutes or hours, and it will involve UX designers, developers and testers, not to mention other stakeholders who might need to sign off the designs.

Subject: Dark Mode best Practise

Hi all,

I am reaching out to find if anyone has any best practise for Dark Mode? We have reviewed the Google documentation and one of my co-workers are researching into Apples docs.  Other than colour contrast, is there any other considerations should be taken into account? Resizing, Reflow and other similar visual SC's would have to pass the WCAG 2.1 standards of course.

Hoping someone can help.

Regards
Sean
