[Icons] Can we get the black icons back?

[davialexandre]

I noticed that the black icon color was removed in 08f301c. Is there any chance to get it back?

Usually, the icon will be black if there is no specific color, but, sometimes, it may end up inheriting the parent color, as you can see in this example: http://jsfiddle.net/davialexandre/5nhbs3h8/
