No green here! Under Windows XP, the ProgressIndicator bar is all grayscale. Your first two examples show gray diagonal stripes shading into white. The third example shows a solid, dark gray bar next to a white bar, with shrinkage of the dark gray portion as time increases. I presume you're working on a different platform? Or, if under Windows XP, with a different theme?
