Termcolor says "ANSI Color formatting for output in terminal."
https://pypi.python.org/pypi/termcolor/1.1.0

It is OS-independent but depends on support of standard ANSI screen 
command codes. Microsoft removed that support from cmd.exe. If you look 
at the Terminal properties box on the page above, the only thing 
termcolor can do on Windows, by itself, is reversed text.  Colorama.init 
adds back (at least some of) the ANSI to API translation omitted from 
cmd.exe.

Because linux terminals translate ANSI to whatever api calls are needed.
