The problem is because you added null=True after creating the migration file. Follow these steps now.

1) Drop ColorSet & Product tables from your local table database.
2) Delete all the migration files you created for these `CharField to a ForeignKey` change
3) execute `python manage.py makemigrations`
4) execute 'python manage.py migrate'
