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?
