CLI background color

[adicl]

I'm using the Alpine version under UNRAID and I have problems with the color of the text in the CLI.
Some of the text (usually debug messages) is displayed black on dark grey background (see attached screenshot) and therefore barely readable. After such a line is displayed also the color of the commands typed afterwards becomes black on dark grey.
Initially I thought that there is a problem with my specific asterisk configuration, or the TERMINAL settings or the Docker configurations....
After some hair pulling I realized that the culprit is the -W from the asterisk command line from docker-entrypoint.sh

if [ "$1" = "" ]; then
  COMMAND="/usr/sbin/asterisk -T -W -U ${ASTERISK_USER} -p -vvvdddf"
else

-W Display colored terminal text as if the background were white or otherwise light in color. Normally, terminal text is displayed as if the background were black or otherwise dark in color.

Given that normally the linux console has a black background I think that this setting is inconvenient for most of the people.
Could you please change this to -B instead or eventually make it configurable?
Of course, you already provided a nice mechanism to override the entire COMMAND, however maybe some people, just like me, will have difficulties to figure out from where the problem comes in the first place.

Thanks and keep up the good work!

Thanks!

There is no option for -B, I will refactor image builder and will make colours options configurable

Thank you very much for considering this small improvement!
Indeed - the -B is not between the switches displayed by the help command - apparently they forgot it - but for sure it is handled in the code:
https://github.com/asterisk/asterisk/blob/7d96b3e43746c2f3a16314acead2be53ee83f3d3/main/asterisk.c#L3570
and it seems to work fine on my side (notice the text background change from dark grey to black)

I see this is still a issue in asterisk 18. When a black notice/warning come in the terminal stays black. Should this not reset to default instead of switching it to black?

Hi, could you test if you have a chance? Fresh new asterisks are there
