Changing the color of Navigation Bar in Windows Phone

Hey,

I am using ContentPage.ToolbarItems to provide options for navigation to different pages. I applied this:
Tint = Color.FromHex("#C2185B")
BarBackgroundColor = Color.FromHex("#C2185B")

But the color of the navigation bar changed in Android and iOS but not in Windows Phone.

Can you please help me with this?
