See the ninja theme for how to extend an existing theme with more regexps and a different configuration.

### Buffering
Note that when you use colout within real time streams (like `tail -f X | qrep Y | colout Y`) of commands,
you may observe that the lines are printed by large chunks and not one by one, in real time.
This is not due to colout but to the buffering behavior of your shell.
To fix that, use `stdbuf`, for example: `tail -f X | stdbuf -o0 grep Y | colout Y`.
