This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

Returns the bit depth of the screen. Per the CSSOM, some implementations return 24 for compatibility reasons. See the browser compatibility section for those that don't.

Value

A number.

Examples

js
// if there is not adequate bit depth
// choose a simpler color
document.style.color = window.screen.pixelDepth > 8 ? "#FAEBD7" : "white";
