One of the built-in tools for Word is real-time spell-checking and grammar-checking. Using the default configuration of the program, Word displays potential spelling errors with a wavy red underline and potential grammar errors with a wavy green underline. This presents a problem for people who may be red-green color blind, as they will not be able to tell which type of error is which on-screen. The solution would be to change the colors of the underlines, but Word doesn't provide a built-in way to make the change.
One possible solution is to play with the color settings for Windows as a whole. You can go to the Appearance and Personalization option (in the Control Panel) and click the Ease of Access Center option. There are several display options available to choose from, including Set up High Contrast. You may need to experiment a bit, but this approach could give desirable results not just in Word, but in other applications as well.
You can also change the colors by modifying some settings in the Windows Registry. The best instructions for how to accomplish this are included in Microsoft's Knowledge Base, at the following page:
