Problem
I see ANSI color sequences on Cygwin.Explanation
The default Cygwin.bat runs bash in a Window terminal, which does not support ANSI sequences, so you'll see the color codes instead of actual colors:$ codecept selfupdate
[37;41m [39;49m
[37;41m [Symfony\Component\Console\Exception\CommandNotFoundException] [39;49m
Solution
Edit the Cygwin.bat and make it look like:@echo off
C:
chdir C:\cygwin64\bin
mintty -
Now, it will run "mintty", which is a different terminal, and it will show the colors correctly.
