Windows appearing grey !!

[sara_9.fi692495]

After I created my plan I started placing windows in walls , but what happened is that they're taking the color of the wall (grey)
how can I make windows look real and not grey ??
(I'm using Revit 2014 )

Check and make sure there is no undelay set to your new plan. This happens and can make things visually crazy at times.
