Need Help: color of objects in any new scenes is gold/grey

If I add a new scene to any project, Objects will have this weird color.
Tried to make a new material color and assign a white color but it doesnt help it, it seems like this happens just to the white color, other colors are fine when I assign them to it.
changing the ambient source to color in lighting window didnt help either.
thanks a lot for the help.

Update: If i create a new scene from the file menu, the colors are fine. but if I just right click in the project "browser" window, Objects are colored weird. But why?
