> Improve log coloring

>                 Key: KARAF-2401
>                 URL: https://issues.apache.org/jira/browse/KARAF-2401
>             Project: Karaf
>          Issue Type: New Feature
>          Components: karaf-shell
>            Reporter: Claus Ibsen
>            Assignee: Jean-Baptiste Onofré
>             Fix For: 4.2.0
> Apache Karaf uses colors in the shell. For example red for ERROR lines in the logs, and
so forth.
> The end user can change these colors in the configuration file, but this is not easy
to do for the average end user.
> It would be great if Karaf offers
> - a command to show the current color settings (with example)
> - a command to change color
> Also down the road it would be great if we could have color themes. So people can easily
switch to another scheme. For example a black/white. And also create their own color themes.
> The default colors is not ideal. For example Windows users has horrible experience as
the red and blue colors is very hard to read on a standard windows DOS prompt.
> There is some way to change the colors in the DOS prompt but Windows people dont know
about this. And frankly it would be nicer if Karaf offered a better out of the box experience.
> Some links about changing colors
> http://tmielke.blogspot.de/2013/04/how-to-chang-colors-in-karaf-shell.html
> Alternatively, you can edit the etc/org.apache.karaf.shell.log.cfg file and add the following
> fatalColor=39
> errorColor=39
> warnColor=39
> infoColor=39
> debugColor=39
> traceColor=39
> See http://en.wikipedia.org/wiki/ANSI_escape_code for standard colours.
> The string is prepended with 0x27 and '[' and suffixed by 'm to build a correct ansi
code, so it should be possible to build more complicated colour strings for blinkings and
> For example the following setting
>     infoColor=1m\0x2739
> will turn on bold with default colour for info statements.
