If you're using a Mac there's an Apple utility (included in the OS X 
installation) called "DigitalColor Meter". It can be used to read
color values in any area of the screen (including "CIE Lab" to three
decimal places). It also allows the adjustable aperture size to be
made larger than Photoshop's eyedropper maximum of 5x5.
