it's neither parameter nor argument

Unless you want to make a more complex data structure, what you want, as I understand it is

cars = {"Ford" : "Blue", "Nissan" : "Red"}

# loop over all cars
for car, color in cars.items():
    print(f'The {car} is {color}')

# or directly access the value for specific key
car = 'Nissan'
color = cars.get(car, 'unknown')
print(f'The {car} is {color}')

a more complex data structure (list of dicts)

cars = [{'make':"Ford", 'color':"blue"}, {'make':"Nissan", 'color':"red"}]

for car in cars:
    print(f"The {car['make']} is {car['color']}")

You can use different data structure, e.g. namedtuple, instead of dict or write your own class, etc.
