If you start having too much fun then decide you want to go back to the way it looked before, click Use Default to reset the colors.

The color for each special date displays in the last column in the grid. To mark multiple days at a time, click Mark/Clear Color for All Days. In the dialog box, you can select all the days that you want to display in the Special Days Color at once.

Want a special day to display in a different color to set it apart from the rest? You can do that, too! When you select a special date in the list, you'll see a color picker under the "On Screen Calendars" section. Select Mark in Color on Calendars then select the color you want for the special date. (If you select the option but don't select a color, the Special Days Color will be used.)

Here are examples of what your color choices might look like on different calendars in your program:
