Office 2007 gives you a choice of three color schemes: blue,
silver, or black. In Word 2007, click on Office Button | Word
Options | Popular | Color scheme: <choose a color> | OK.
You can also experiment with turning on the "high contrast"
setting in Windows:
• In Windows XP, click on Start | Control Panel | Accessibility
Options | Display tab | check the "Use high contrast" box | OK.
• In Windows Vista, there should be an option to turn on high
contrast somewhere in Start | Control Panel | Ease of Access
Center. You can also toggle high contrast on or off by pressing
Alt+LeftShift+PrintScreen.
The Windows high contrast setting will modify the shades of color
in Office 2007's blue, silver, or black color schemes, but the
setting also affects all of your other programs, which may not be
desirable.
