The color palette used in your Tracker™ Version 5 software is based on your Windows settings.  To change the colors, simply navigate to your "Display Properties" and select the "Appearance" tab.  You can then select from a list of preformatted color schemes or customize the colors to whatever you choose.  The interface screens in Tracker Version 5, as well as the progress graphs and other visual aspects of the program, will conform to the new palette you have chosen.

Note: Changing the Windows color settings may affect how other programs display colors.
