To view these colors correctly, you should have your monitor set to "High Color-16bit" or "True Color-32bit". (32,000 colors or MORE!) This will NOT display correctly in 256 or 16 color modes.
To change settings in Windows, right click the desktop and choose Properties, then click the Settings Tab and adjust Colors. You may have to adjust the Screen Area as well to produce enough colors, depending on your video adapter. Note the present settings before changing them if you wish to return to your previous settings.
