The color-index CSS @media media feature can be used to apply styles based on the number of entries in the output device's color lookup table.


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.


Basic example


<p>This is a test.</p>


p {
  color: black;

@media (color-index) {
  p {
    color: red;

@media (min-color-index: 15000) {
  p {
    color: #1475ef;


Custom stylesheet

This HTML will apply a special stylesheet for devices that have at least 256 colors.

<link rel="stylesheet" href="" />
<link rel="stylesheet" media="all and (min-color-index: 256)" href="" />
