The CSS font-palette property allows selection of a specific palette used to render a font. For this property, CSS Fonts 4 defined the animation behavior of this property as discrete, which is insufficient to achieve a smooth transition between two selected palettes. Similar to other color transitions in CSS animating the font-palette property should happen by interpolating each of the color record values between start and end palette.
