font-palette

The font-palette CSS property allows specifying one of the many palettes contained in a color font that a user agent may use for the font. Users can also override the values in a palette or create a new palette by using the {{cssxref("@font-palette-values")}} at-rule.

[!NOTE] A font-palette palette takes precedence when coloring a font. The {{cssxref("color")}} property will not override a font palette, even if specified with {{cssxref("important", "!important")}}.

Syntax

css

/* Using a font-defined palette */
font-palette: normal;

/* Using a user-defined palette */
font-palette: --one;

/* Creating a new palette by blending two others */
font-palette: palette-mix(in lch, --blue, --yellow);

Values

normal
- : Specifies the default color palette or the default glyph colorization (set by the font maker) to be used for the font. With this setting, the palette in the font at index 0 is rendered.
light
- : Specifies the first palette in the font that matches 'light' to be used for the font. Some fonts contain metadata that identify a palette as applicable for a light (close to white) background. If a font does not have this metadata, the light value behaves as normal.
dark
- : Specifies the first palette in the font that matches 'dark' to be used for the font. Some fonts contain metadata that identify a palette as applicable for a dark (close to black) background. If a font does not have this metadata, the value behaves as normal.
<palette-identifier>
- : Allows you to specify your own values for the font palette by using the @font-palette-values at-rule. This value is specified using the <dashed-ident> format.
{{cssxref("font-palette/palette-mix", "palette-mix()")}}
- : Creates a new font-palette value by blending together two font-palette values by specified percentages and color interpolation methods.

Examples

Specifying a dark palette

This example allows you to use the first palette marked as dark (works best on a near black background) by the font-maker.

css

@media (prefers-color-scheme: dark) {
  .banner {
    font-palette: dark;
  }
}

Animating between two palettes

This example illustrates how to animate font-palette value changes to create a smooth font animation.

HTML

The HTML contains a single paragraph of text to animate:

html

<p>color-palette
animation</p>

CSS

In the CSS, we import a color font called Nabla from Google Fonts, and define two custom font-palette values using the {{cssxref("@font-palette-values")}} at-rule. We then create {{cssxref("@keyframes")}} that animate between these two palettes, and apply this animation to our paragraph.

css

@import "https://fonts.googleapis.com/css2?family=Nabla&display=swap";

@font-palette-values --blue-nabla {
  font-family: "Nabla";
  base-palette: 2; /* this is Nabla's blue palette */
}

@font-palette-values --grey-nabla {
  font-family: "Nabla";
  base-palette: 3; /* this is Nabla's grey palette */
}

@keyframes animate-palette {
  from {
    font-palette: --grey-nabla;
  }

  to {
    font-palette: --blue-nabla;
  }
}

p {
  font-family: "Nabla", fantasy;
  font-size: 5rem;
  margin: 0;
  text-align: center;
  animation: animate-palette 4s infinite alternate linear;
}

Result

The output looks like this:

{{EmbedLiveSample("Animating between two palettes", "100%", 300)}}

[!NOTE] Browsers that still implement discrete font-palette animation will flip between the two palettes rather than smoothly animating.
