Customizing logback color scheme - scala

Question

I have been messing with my logback coloring and Im wondering if I can change the highlighting colors. Right now I have this
Which is ok, but I would like to make info blue, warnings yellow and errors non-bold red or something along those lines. Is that possible? Also, is it possible to select different colors for the logger name highlighting? For instance, if I wanted com.blah to be cyan and org.apache logger magenta or something else? My current pattern is
<Pattern>%d{HH:mm:ss.SSS} %highlight(%-5level) [%thread] %cyan(%logger{36}) - %highlight(%msg%n)</Pattern>
This is a Scala project with SBT and I use logback for logging if that makes a difference.

Answer 1

Yes, judging from the Spring ColorConverter this should be possible with a bit of custom code. See the default Spring logback configuration.
For coloring JSON output with Logback Logstash, I've written (shameless plug) this project in which the same type of functionality can be added.

Answer 2

the bellow works for me
Java Code
package com.acme.logback;
public class MyCustomHighlighting extends ForegroundCompositeConverterBase<ILoggingEvent> {
#Override
protected String getForegroundColorCode(ILoggingEvent event) {
Level level = event.getLevel();
switch (level.toInt()) {
case Level.ERROR_INT:
return ANSIConstants.BOLD + ANSIConstants.RED_FG; // same as default color scheme
case Level.WARN_INT:
return ANSIConstants.RED_FG;// same as default color scheme
case Level.INFO_INT:
return ANSIConstants.CYAN_FG; // use CYAN instead of BLUE
default:
return ANSIConstants.DEFAULT_FG;
}
}
}
Logback.xml
<configuration>
<!-- custom coloring conversion -->
