When using the integrated powershell terminal with VSCode, colors are taken into consideration from
- The VSCode theme
- The colors set in Powershell itself
I recommend matching both color schemes as closely as possible to make life easier for yourself.
For setting the powershell colors use this application which actually works: https://github.com/lukesampson/concfg I tried other tools like ColorTool already to no avail
Ensure you haven't already overridden any Powershell colors in this file $profile
I personally use concfg import cmd-default
and the VSCode theme Dark+ (default dark) and have no problems seeing anything.
If you really do want to override the terminal colors from VSCode in addition to taking the defaults from the VSCode theme try looking into the setting workbench.colorCustomizations
for your user .vscode
file.
