Sometimes for emphasis adjectives or paired adjectives follow the noun they modify. The adjective or adjective pair is then set off by commas.
Correct: The car, bright red, stood out in the parking lot.
The adjective pair, if coordinate adjectives, must use the word and to separate the two adjectives.
Correct: The dessert, sweet and rich, was delightful.
