I have the same experience as Pete, I used a bad theme hack to get a dark theme, and context menus where white font on white background. Also, getting this to work was cumbersome. SQL Shades just works! Just install it, the next time you open SSMS it will change to the dark theme. For people with bad eye sight this is a game changer, no more white to strain my eyes.

Shades is the dark mode add-in for SQL Server Management Studio.
Just install the SQL Shades extension and it'll darken everything automatically, including what SSMS' hidden dark mode misses.
