The Screen.colorDepth
read-only property returns the color depth of the screen. Per the CSSOM, some implementations return 24
for compatibility reasons. See the browser compatibility section for those that don't.
Syntax
bitDepth = window.screen.colorDepth;
Example
// Check the color depth of the screen if ( window.screen.colorDepth < 8) { // Use low-color version of page } else { // Use regular, colorful page }
