Use the StartColor and EndColor properties to specify the indicator's color. By default, these properties have equal values and the indicator has a solid fill. You can, however, specify different values for these properties to provide a gradient fill.
Note
The colors specified by the StartColor and EndColor properties are only in effect if the progress bar is painted using the Flat, UltraFlat or Style3D style. To change the progress bar's look and feel settings, use the RepositoryItem.LookAndFeel property.
