Color
When you select a file on your Mac or some words in a word processing document, the computer indicates this by highlighting the item. When Apple added color to the Mac it then opened up the world of color to this mundane little task.
So, in one more small way you can personalize your Mac by changing this highlighting color through the Color control panel.
You can choose from a selection of standard colors, or by taking the Other option, you can choose any color you like from the Apple color wheel (give this a try, its fun).
Similarly, with the WIndow Color option, you can change the color that outlines the title bar of active windows — although this one is pretty subtle, but check it out for yourself.
