Most parameters include a color control. By clicking the color preview square to the left of the checkbox label, the Color Picker dialog will appear. This is the same standard Color Picker used by many other Windows® applications, so its function should be familiar to most Windows users.
You may select any custom color you wish, and every parameter may have its own unique color. The Color Picker allows up to 16 custom-colors to be defined; color choices can be saved to the Windows registry as user defaults.
