It'd be great to see support in WebKit, after Google Chrome plans to ship support for this format, and Mozilla and Microsoft have expressed a positive standards position on the format. It also integrates very nicely with WebKit's recent addition of supporting font-palette. Thanks for considering.

The intention of filing this issue is to have format support in WebKit, as a feature available on the web. Whether that supports originates from platform libraries (as it's done traditionally through CoreText in Safari), or in higher layers is an architectural choice: It's probably possible to implement support for CORLv1 based on FreeType and the platform graphics contexts that WebKit's architecture provides an abstraction for. 1819703 3 webkit-bug-importer 2021-12-02 08:14:20 -0800 <rdar://problem/85971830> 1844164 4 akiem 2022-02-21 04:44:55 -0800 From a type designer point of view, it would be great to have a better support of the COLRv1 table. For me, one of the key features it provides is not the colors, but that we can also use it as a more advanced glyf table. Using only the foreground color, you get everything that the current glyf table provides + a lot of other stuff like transformations, compositing, blending, layering. This makes COLRv1 very different from other color-related tables like SVG, COLOR (version0), six... 1955344 5 woodlxf00 2023-05-14 22:33:24 -0700 OpenType 1.9 has been released for a while now. https://learn.microsoft.com/en-us/typography/opentype/spec/ And both Chrome and Firefox has supported it. https://caniuse.com/colr-v1 Is it any change on position? Will it been implemented in future milestones? 1955451 6 mmaxfield 2023-05-15 10:37:48 -0700 If it existed, implementation would be in the platform text libraries in macOS/iOS, not in WebKit. We cannot comment about that. 2061331 7 woodlxf00 2024-09-18 20:57:52 -0700 I don't know whether it depends on OS or not. But how did Chrome do with it in Mac OS?
