color-index

The color-index CSS media feature can be used to test the number of entries in the output device's color lookup table.

Syntax

The color-index feature is specified as an <integer> value representing the number of entries in the output device's color lookup table. (This value is zero if the device does not use such a table.) It is a range feature, meaning that you can also use the prefixed min-color-index and max-color-index variants to query minimum and maximum values, respectively.

Examples
