Adjectival Comma Query

That comma is completely wrong.

See this site and

Thanks for those links, but where do ones like these come in?

1. He is wearing a black, high-top hat
2. There is a black, crystal stone right under his name.
3. He slides his right hand down the black, steel railing.

Should the commas be removed because the first adjective is just a colour?

Thanks.

SnarfHe is wearing a black, high-top hat

I’ve heard of a top hat, and I’ve heard of a high hat, but not a high-top hat. In any case, the comma is wrong.

SnarfThere is a black, crystal stone right under his name.

I would not use a comma there.

SnarfHe slides his right hand down the black, steel railin

Aspara GusIf you had truly studied the links I provided, you would not have asked these questions.

I did, but I just wanted to make sure, since they do not speak of colours. And I already knew about the and test, but I have noticed that it doesn't always apply. For example:

He wore a wide, black hat.

My first link does. Upon clicking it, you will be prompted to download an MS Word document. The article is not viewable on the website itself.

SnarfI can say, "He had a wide and black hat" and the second site uses the example of "heavy, bulky," but I still ge

Oh, so "long black curly hair" is a conventional use of cumulative adjectives, just like big old shaggy dog is. Very interesting.

Yes, I will definitely keep that Word doc, and thank you for it. It will come in very handy, I'm sure.

What if the quality comes at the end, after age and colour? For example:
They had all been getting drunk around a new, black, shiny BMW the entire time.
Should those commas stay because it's not longer "conventional" in its cumulative order, according that chart?
Thanks.

The order of those adjectives looks awkward to me. I would change the order and use one comma: a new, shiny black BMW or a shiny, new black BMW.

Oh, I see. What about where it's three cumulative adjectives in a conventional order, but where one adjective might look too connected to the last one? For example:

She had long straight blonde hair.

At this point I'm about 85% sure that there is no comma needed there, but does straight look like it's describing the word "blonde" rather than "hair," hence making it

No comma, no confusion.
