I have seen that coordinate adjectives work independently from each other, belong to the same category, and can be separated with commas or the conjunction "and" and still sound normal even if their order is changed.
A beautiful, silent car.
A silent, beautiful car.
(Both beautiful and silent are matters of opinion)
On the other hand, cumulative adjectives have to build upon each other and belong to different categories, such as size (big, small, large) and material (metallic, gold, plastic).
A large metal tube.
However, I can think of some sentences where you have two adjectives that belong to different categories and still sound fine like coordinate adjectives. For example:
She had a frail, small body.
She had a small, frail body.
(Frail is a matter of opinion, while small is a matter of size)
What gives? Is it possible that some adjectives can belong to different categories and still be used in a sentence like coordinate adjectives?
