Microsoft SQL Server Studio - Dark Mode

Run this Python code as Administator.
SSMS 19 added, modify the path to your SSMS installation folder if need.

You might want to give SQL Shades a try - I've been using it a short time and its better than the old hacky solutions. https://www.sqlshades.com/

None of these solutions apply to SSMS v19+. You are on your own.
The world loves bright white light for some reason. Enjoy finding a way to obtain a Dark Mode in SSMS v19+. In the past I have used the following:- Options

• Environment
• Fonts and Colors You can experiment here and tame down the bright white light. Then after a while you WILL find something that works and be able to be productive. Maybe in the next 20 years, Dark Mode will catch on as users' eyes can't take it any longer!
