override-colors

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since November 2022.

The override-colors CSS descriptor is used to override colors in the chosen base-palette for a color font.

Syntax

/* basic syntax */
override-colors: <index of color> <color>;

/* using color names */
override-colors: 0 red;

/* using hex-color */
override-colors: 0 #f00;

/* using rgb */
override-colors: 0 rgb(255 0 0);

/* overriding multiple colors */
override-colors:
  0 #f00,
  1 #0f0,
  2 #00f;

/* overriding multiple colors with readability */
override-colors:
  0 #f00,
  1 #0f0,
  2 #00f;

The override-colors descriptor takes a comma-separated list of the color index and new color value.

The color index is zero-based and any color value can be used.

For each key-value pair of index and color, the color with the index in the specified base-palette will be overwritten. If the color font does not have a color at the specified index, it will be ignored.

Values

[ <integer [0,∞]> <absolute-color-base> ]

Specifies the index of a color in a base-palette and the color to overwrite it with.
