Remarks

If you retrieve the value of the pixelDepth property through a script, you can select an appropriate color to return to the browser.

If bufferDepth is 0 or -1, pixelDepth is equal to the bits-per-pixel value for the screen or printer.

If pixelDepth does not equal zero, pixelDepth is equal to colorDepth.
