django logging: DJANGO_COLORS does nothing (macos)

Question

I'm on MACOS terminal. I'm trying to print colored output running a django test. I'm setting, from the terminal

export DJANGO_COLORS="error=yellow/blue,blink;notice=magenta"

(also tried DJANGO_COLORS="light" and others.

Then, from django test code

print(os.environ['DJANGO_COLORS'])
logger.error("test")

and run

python manage.py test

The first line verifies that the environment variable is set correctly. But the next line prints normally, without coloring. What is wrong?

From the django-admin syntax coloring documentation that deals with DJANGO_COLORS (emphasis mine):

The django-admin / manage.py commands will use pretty color-coded output if your terminal supports ANSI-colored output.

That doesn't mention output from the logging package. The referenced commands use a specific kind of stdout.write invocation that should take DJANGO_COLORS into account.

If what you want is colors in your logging, you might want to check out the answers to this relevant question.

So, no built-in way for colorful logging? – blue_note Nov 07 '18 at 10:30
If you check out the last link, I think you should be able to get colorful logging working. It's just not Django-specific, and not nearly as pretty. – kungphu Nov 07 '18 at 12:47

from django.core.management import color_style
sys.stdout.write(color_style().WARNING("Colorful!"))
