Normally when you look for files in the Finder window, all files appear as icons and a name. Trying to find the one file you want out of a dozen or more files can be like trying to find a single airline flight on a screen full of a dozen other airline flight listings.
To make visually browsing for a file much easier, you can identify it by one of seven color labels: red, orange, yellow, green, blue, purple, or gray.
Here's how to label a file or folder with a color:
Click the Finder icon on the Dock. A Finder window appears.
Open the drive and folder that contain the file or folder you want to label with a color.
Click the file or folder you want to label with a color.
Select File ▸ Get Info, or press -I. A Get Info window appears, as shown in Figure 14-1.
Click the close button of the Get Info window. The name of your chosen file or folder now appears highlighted in your chosen color.
For a faster way to add a color label to a file or folder, right-click that file or folder to display a pop-up menu. Then click a color label, as shown in Figure 14-2.
