Different color for taskbar and active window

Since windows 8.1 update 1, the registry tweak to have different colors for the active window and the taskbar has disappeared.
The tweak made it possible to have white windows and a colored taskbar, which was already far from perfect.
The active windows used to have a distinctive blue heading, and the task bar was a readable grey, in classic mode.
Since windows 8, they have the same color, which results in a difficult readable taskbar (I never receive letters printed on blue paper, for obvious reasons), or guessing what the active window is, because when you choose a readable grey, all the windows look almost the same, active or not, especially if you have more than 1 monitor, which have slightly different colors.

So I would like to have this feature implemented, I think it will make a lot of people happy.
