[css-color-adjust] Should dark mode apply to favicons?

[chrishtr]

I think it should. This doesn't seem to be in the spec, just make a simple addition?

See also this Chromium issue.

Can you clarify what you mean by "apply"?

[chrishtr]

i.e. Should a dark mode theme apply to the document containing the SVG favicon, thereby adjusting its default background and foreground colors, etc?

[fantasai]

@chrishtr It should be handled no differently from any other linked/embedded SVG document. If it's an external document, it won't inherit any CSS properties, because those don't inherit through such links. But it should be given the same @media environment, and should follow the same rules as the loading of any other SVG document. We don't make any exceptions for favicons, so I don't see why that wouldn't be the case already.

Is there something you think should be happening that's an exception to the normal way we handle SVG documents?

[chrishtr]

Ok, this makes sense. The spec for them in HTML also says it has the same @media environment: https://html.spec.whatwg.org/#rel-icon

Is there something you think should be happening that's an exception to the normal way we handle SVG documents?

No, I just wanted to make sure favicons would get the same color scheme and that this is in the spec.

The Chromium bug in this description is for devtools emulation, not favicons in the "normal" case.

There was an issue with SVG favicons not being rendered with the correct prefers-color-scheme, but that has been fixed: https://crbug.com/1090464
