Changing the progress bar color

[Jerry Mulchin <jmulchin astroguy com>]

I'm trying to change the progress bar's color from the default dark gray
to various colors, depending on what's going on behind the scenes. Is
there an easy way to do this, like a gtk function call to just set it?

Thanks in Advance
