color

The color CSS media feature can be used to test the number of bits per color component (red, green, blue) of the output device.

Syntax

The color feature is specified as an <integer> value that represents the number of bits per color component (red, green, blue) of the output device. If the device is not a color device, the value is zero. It is a range feature, meaning that you can also use the prefixed min-color and max-color variants to query minimum and maximum values, respectively.

Note: If the various color components are represented by different numbers of bits, the smallest number is used. For example, if a display uses 5 bits for blue and red and 6 bits for green, then the device is considered to use 5 bits per color component. If the device uses indexed colors, the minimum number of bits per color component in the color table is used.
