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.
