override-colors
Baseline 2022
Newly available
Since November 2022, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.
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:

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

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