I change the color theme of Visual Studio to dark. It's very cool, especially for my eyes.
I also very often use Microsoft SQL Server Management Studio. The problem is when I change from Visual Studio to SQL Server Management Studio it's a pain for my eyes.
Is there is a simple way to change SQL Server Management Studio's theme to dark, too?
Check out the link below for a .zip file that contains a Visual Studio project. Open the project and if necessary, edit the SRC_KEY and DEST_KEY strings to reflect the versions of Visual Studio and SQL Server you're running. I believe the GUID value of the key remains unchanged.
After you run the project and it finishes successfully, open up SQL Server Management Studio, go to Tools -> Options. Then click "Environment" on the left, and then "Fonts and Colors." You should see they have changed to dark ones. Just click the "OK" button and you should be good to go.
If you're wary of copying registry values, just make a backup of your SQL Server registry settings. Good luck; I hope that helps!
