palette-mix()

Functional notation:

palette-mix(method, palette1 [p1], palette2 [p2])

method

A <color-interpolation-method> specifying the interpolation color space.

palette1, palette2

The font-palette values to blend together. These can be any font-palette values, including palette-mix() functions, normal, dark, and light.

p1, p2 Optional

<percentage> values between 0% and 100% specifying the amount of each palette to mix. They are normalized as follows:

• If both p1 and p2 are omitted, then p1 = p2 = 50%.
• If p1 is omitted, then p1 = 100% - p2.
• If p2 is omitted, then p2 = 100% - p1.
• If p1 = p2 = 0%, the function is invalid.
• If p1 + p2 ≠ 100%, then p1' = p1 / (p1 + p2) and p2' = p2 / (p1 + p2), where p1' and p2' are the normalization results.

This example shows how to use the palette-mix() function to create a new palette by blending two others.

HTML

The HTML contains three paragraphs to apply our font information to:

<p class="yellowPalette">Yellow palette</p>
<p class="bluePalette">Blue palette</p>
<p class="mixedPalette">Mixed palette</p>

CSS

In the CSS, we import a color font from Google Fonts, and define two custom font-palette values using the @font-palette-values at-rule. We then apply three different font-palette values to the paragraphs — --yellow, --blue, and a new green palette, created using palette-mix() to blend the blue and yellow palettes together.

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

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

@font-palette-values --yellowNabla {
  font-family: Nabla;
  base-palette: 7; /* this is Nabla's yellow palette */
}

p {
  font-family: "Nabla";
  font-size: 4rem;
  text-align: center;
  margin: 0;
}

.yellowPalette {
  font-palette: --yellowNabla;
}

.bluePalette {
  font-palette: --blueNabla;
}

.mixedPalette {
  font-palette: palette-mix(in lch, --blueNabla 55%, --yellowNabla 45%);
}

Result

The output looks like this:

• font-palette
• @font-palette-values
• color-mix()
• Color spaces and color models for information about color spaces
