Changing greyscale of progress

[onnel]

As time passes, the active spells are slowly covered up with grey (to nidicate how much of their duration is past). The problem is, they grey that covers them isn't dark enough for me.

How can I darken the "progress" colour on the progress bars for active spells?

I looked in the xml and the only thing I found was "progress_grayscale_fill". i have no idea if that's really the property for what I'm looking for.

The other problem is that it is only a reference to a sourcerect in a DDS file.

What do I need to do to change the colour?

All help much appreciated!

Thanks!

P.S. Same goes for the hotkeys..I'd like they greying over as they "reactivate" to be more extreme.
