Right now modd overwrites the colors of subprocesses. It would be nice if those colors were preserved.

modd doesn't remove the colors. Most programs will detect whether their output is being sent to a pipe and adjust accordingly, i.e. remove colorization codes.

There are some workarounds, discussed here:

For me unbuffer does the trick. On my linux distro it's included in the package expect. See here for OSX and here for Linux.

Add a modd config for colorized elm-make output
d84e648 
Elm compiler is able to produce helpfully colorized error messages.
Unfortunately these colors won't make it through webpack and elm-webpack-loader.

As a workaround we can optionally use modd alongside with webpack.

Even with modd elm-make will output color-codes only if output goes to a terminal,
not through a pipe. There are several ways to do this, see:
cortesi/modd#26

Here we use the utility `unbuffer` from the the tool `expect`, which is available
for most Linux distros and for OSX.

unbuffer worked for me. Is there any way to notify the user that this might be occurring and output some kind of helper ("You may need unbuffer to retain colorized output of subcommands")?

Dear people, I'm on Windows and I'm using daemon: go run . with a simply default chi router.

Any hint for show colors?

I've just added an explanatory note about colourized output to the README. Let me know if you feel that this needs any expansion or clarification.
