Specificationhttps://drafts.csswg.org/css-fonts-4/#font-palette-prop Summary The CSS font-palette property allows selection of a specific palette used to render a font. The CSS Fonts 4 spec defines the animation behavior of this property as discrete, which is insufficient to achieve a smooth transition between two selected palettes. Instead, animating the font-palette property should happen by interpolating each of the colour record values from the defined palette, i.e. if the start or the end of the animation has a different colour value for some record in the palette, such colour value should be interpolated.

Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).
