What are the rules for Bamboo build log coloring?

[Mike Friedrich]

This question is in reference to Atlassian Documentation: Viewing a build log

I am running a custom script and have full control about what is shown in the build log.

Some lines in the build log are red, they are not errors. What is the rule for the coloring?

From what I can tell - anything that is written to STDERR gets a "red" color.  Anything written to STDOUT is a black color.  I've noticed that a lot of "helper" tools tend to write to both (capistrano output, most ssh boilerplate output, etc), so they get colored as "red".

Thanks, i am using set -x in bash and was confused why the commands are printed in red.

After some digging i found out that it is because these commands are printed to stderr by default.
