Make progress bars less grim

Hello there! First of all, thanks for this cool software!
I was wondering if it would be a good idea to make progress bars on cards less grim and black. The gloom is especially noticeable when there are several cards with progress bars close to one another, like in my case here:

Could the bars perhaps change color when they are close to completion? Start at red, and then go through yellow to green?


I would avoid adding more colors to it. But I think they could get a lighter shade of grey instead. I’ll try something out.

What about something like this?


That does look better indeed!
Somehow I still think that a visual distinction when the progress bar is complete would be cool, but in the end it seems to be a matter of taste.

Changed to a lighter grey in bdf7af010c.
