Coordinate Adjectives and The Royal Order of Adjectives

Adjectives!  How do you know when to put a comma between them?  

Cumulative Adjectives just pile up.
It would sound strange to put "and" between them
or to reverse them.
They do not need commas between them.

Coordinate Adjectives are Equal.
You could use "and" between them.
You could reverse them.
Place commas between them.

    

WHAT DO YOU SEE WHEN YOU LOOK AT THE IMAGE ON THE ABOVE?

A little red Italian sports car?  Or a sports red Italian little car? How about a little sports Italian red car?

What is it about the first option that rings true to the ear while the others do not? It’s a rule of word order we call “The Royal Order of Adjectives.”

 If they are coordinate or equal, add the comma. 
Two quick tricks to check for coordinate commas are
       a. replace the comma with "and," and
       b. reverse the order of the adjectives.
   If those work, you need a comma. 

 If they are in the same column in this chart, they are coordinate or equal.

Remember:
                     What qualifies as an observation?
                     Size comes before  color.
                     Do not put a comma between the last adjective and the noun.
                     Do not put a comma between the noun and the verb.
