2. 2.       When the Magnifier application opens, your screen will be zoomed in. Click the negative button (-) until you're zoomed out all the way
3. 3.       Click on the gray gear to open the "Preferences". Put a check in the box that says "Turn on color inversion." Then click "OK" to finish inverting your colors. The options for the Magnifier do not change if you leave the application, so you will only need to do this  once.
