I am trying to enable xterm 256 color via git bash. It turns out there are 2 ways to start a git bash in Windows.
- windows cmd, run this
git-cmd.exe --command=usr/bin/bash.exe -l -i - mintty, run
git-bash.exe
However seems only the second one support 256 color. The following screenshot is executing result of cat AnsiColors256.ans AnsiColors256.ans.

But the downside of git-bash.exe is that it can't be integrated into integraded command line tool like ConEmu, as indicated on ConEMU Doc
Also, you may run in ConEmu tab git-bash.exe, but this is not recommended, because it runs mintty.exe, which is another terminal.
It actually start an new window instance.
My question is, is there any tweak to config cmd.exe to support 256 color like mintty.exe? I still want to use a single ConEMU instance for all my command line interfaces.
I am using windows git version git version 2.24.0.windows.2
