How to use keywords for logfile coloring

[MrPrezident]

I noticed that is pull request was merged earlier this year which enables logfile coloring based on keywords:
#39006

I am trying to figure out how to update the keywords for my DAG. There are some lines in my logfile that are not warnings or errors, but they are important information that I need to be able to see at a glance, so I would like to color them. I want the coloring to only apply to a specific DAG though. How can I do this? I noticed that these were added to the config.yml and that they have default values:
color_log_error_keywords
color_log_warning_keywords

How can I define the non-default values for my DAG and is there a way to have a separate color for non-errors/non-warnings?
