Color words are adjectives. We can modify a noun by using a color word in front of the noun.

We also use adjectives to show the age of a noun. These adjectives modify a noun by showing its age:
old, new, elderly, young, ancient, newborn, fresh, stale, teen-aged, middle-aged
The ancient house was built in the 1800s.
I heard a newborn baby crying.
Mom said to use the fresh bread for our sandwiches.

We use adjectives to show the color of a noun and the age of a noun.
