I created a new model and registered it to admin.py but when I am running python manage.py makemigrations it showing that no migrations to apply

In models.py:

from colorfield.fields import ColorFieldclass colour(models.Model):    color=ColorField(format="hexa")    def __str__(self):        return str(self.id)

In admin.py:

admin.site.register(colour)

When I am running python manage.py makemigrations it says:

System check identified some issues:WARNINGS:?: (urls.W005) URL namespace 'userauths' isn't unique. You may not be able to reverse all URLs in this namespaceNo changes detected

And when I am running python manage.py migrate it says:

System check identified some issues:WARNINGS:?: (urls.W005) URL namespace 'userauths' isn't unique. You may not be able to reverse all URLs in this namespaceOperations to perform:  Apply all migrations: admin, auth, contenttypes, sessionsRunning migrations:

Now When I am going to admin pannel there is a table called colour but when I am clicking it there is an

no such table: core_colour
