You do not need ‘comma’ between adjectives when a noun is preceded by many different type of attributive adjectives. In the following example, the attributive adjectives are underlined.
e.g. Two large red cardboard milk cartons.
In this example, two is a cardinal number, large is an adjective indicating size, red is an adjective indicating color, cardboard is an adjective indicating a type of material, and milk is a defining adjective indicating purpose.
However, when you use more than two predicate adjective, a comma is necessary after the first and the last being joined by conjunction ‘and’.. as:
The weather is clear, cold and dry.
