Can you please provide details on how you came to the conclusion that Safari 26 removed support for this feature?

I built safari-color-tinting to demonstrate and document this change.

Can you confirm that you checked both in desktop and mobile versions, and if you used one of the linked examples, can you confirm that you verified a prior Safari version like 18.6?

Yes. I have used safari-color-tinting to show that Safari 26 (macOS and iOS) drops support for theme-color and that Safari 18.x (macOS and iOS) only uses theme-color.

@caugner, thank you for taking a second look.

@andesco Could you add screenshots to the PR description?

I don't see any differences between Safari 26, 18.4, and 17.3, and I don't find the mentioned setting neither in Safari 17.3 nor Safari 18.4:
