This works on the app with few lines of codes:
coloredlogs.install(logger=logger, level=logging.DEBUG, fmt=fmt_term, datefmt=datefmt)
but at my big app setting explicit logger looks like disabling coloring at all;

this color my logs - but for all libraries - that I do not need:
coloredlogs.install(fmt=fmt_term, datefmt=datefmt)
