If you are a web designer or do any work matching colors with photos, you are in luck. Mac OS X comes with a cool little program to help you get the digital value of any pixel on the screen. It's called Digital Color Meter. Here is how to do it: From the 'Finder' menu, choose 'GO->Utilities' Next, open the app, 'Digital Color Meter' Now, you can change the aperture size to smaller (left) or larger (right). Also, you can use the drop down menu to choose what format you want it represented in. For HTML coding, I use RGB As Hex Value, 8-bit. Your needs may be different, and it gives you several options to choose from.
