Adjective defining a property of an object that is possessed by many of those objects

Question

Is there a word defining an object's property possessed by many similar objects? Something like this:

Tommy bought a red balloon at the circus. Many kids have red balloons there. Hence ballon's color is <the word I am looking for>.

Answer 1

I think you might be thinking of ubiquitous, which means that it is found everywhere.

Every child had a red balloon. The color red was ubiquitous.

Answer 2

One adjective would be common:

happening often; existing in large numbers or in many places

• Jackson is a common English name.
• Breast cancer is the most common form of cancer among women in this country.
• Some birds which were once a common sight are now becoming rare.
• a common spelling mistake
• Allergies to milk are quite common in childhood.

So, because there are so many red balloons, Tommy's balloon color is common.

Answer 3

Words such as typical, ordinary, or average might be good options here.
