Windows 8 As of now has no direct way which allows you to choose different colour settings for its Metro UI i.e. For example if you want to have different colour scheme for Charm Sidebar and something different for Logon Screen. I think probably the feature is locked as of now in the developer preview and Window 8 has similar Theme style as Windows 7
Metro UI Color Changer
Door 2 Windows has releases a small utility which can help you change this color scheme for Windows 8 which is easier than the application which we used to change the Metro UI Background .
This application can change color for :
- Start Screen and Logon Screen
- Start Screen Tiles
- Start Screen Tiles Fonts
- Charm Sidebar
- Charm Sidebar Item Hover
- Network Charm Item Hover
- Charm Sidebar Item Selected
When you launch the application it shows the default scheme and if you want to restored to default, it can be done anytime using the same application. Make sure you launch the application with admin privilege or run as administrator.
