[logback-user] ANSI coloring?

That sounds suspiciously like someone forgot to reset the terminal code back to normal from red.

Here's what we use in our encoder:

  // Attribute codes:
  // 00=none 01=bold 04=underscore 05=blink 07=reverse 08=concealed
  //
  // Text color codes:
  // 30=black 31=red 32=green 33=yellow 34=blue 35=magenta 36=cyan 37=white

  public static final String COLOR_YELLOW   = "\033[1;33m";
  public static final String COLOR_NEUTRAL  = "\033[0m";
  public static final String COLOR_ALL      = "\033[0m";
  public static final String COLOR_ERROR    = "\033[01;31m";
  public static final String COLOR_WARN     = "\033[01;35m";
  public static final String COLOR_INFO     = "\033[01;34m";
  public static final String COLOR_DEBUG    = "\033[01;36m";
  public static final String COLOR_TRACE    = "\033[0;37m";
  public static final String COLOR_DEFAULT  = "\033[0m";

After every log statement, we have to append COLOR_DEFAULT to change it back to normal (we color our entire log message the same color).
