Gets the color of a ProgressBar.
A ProgressBar is filled with a vertical gradient between this color and a brighter color computed from it. This style has no effect on other components, but can be set on a container to control the appearance of all progress bars found within. The default value is undefined, which means it is not set. In this case, the themeColor style property is used.
