Color of adb logcat in Ubuntu command line
I use a python script I found here :
Modifying the Android logcat stream for full-color debugging
It's really easy to use and to modify if you want.

If you have NPM, you could install module:
$ npm install -g logcatthat will provide you to start monitoring colored logcat in console and //127.0.0.1/.
$ logcatHere is description
I wanted something dead simple and didn't want to import some gigantic script that parses and reformats the output, so I came up with this. This literally just prints exactly the input line, adding color codes accordingly.
