Is it possible for an adjective to modify another adjective?

While I doubt an adjective can modify another one, I'm wondering if it may be possible. Here is the example: "An immaculate black three-piece suit." Most likely, I'd have to use the adverb immaculately to modify black, but I could be wrong. What syntactic parses are possible for “an immaculate black three-piece suit”?

(Also, if someone has an answer as to why bright in “a bright red car” is grammatical, I’m all ears. Bright is an adjective meaning—in that context—vivid and bold [as Oxford defines it], yet it is modifying a second adjective: the color red. Is bright, or any other word describing color, like light in light red, the only adjective that can get away with this?)

Solution 1:

Let's say the noun Joe wants to describe is the paper he just wrote. It has more pages than the average, so one adjective is long. We want to modify the way "long" describes the "paper", so we look for some words to make the modification.

Do we want an adjective? No, because "long" is not a noun, though it can be made a noun when you change it to "length". Rather, it is doing something to the word "paper" by describing it, so if we want to modify the description, we need to add an adverb.

For example, if we want to clarify that it is not necessarily among all papers that Joe's is regarded long, but only among this topic, then we might say "Joe wrote a relatively long paper".

Solution 2:

an immaculate black three-piece suit

The absence of punctuation marks this as the 'stacking' of modifiers. Here there are two layers of modification: "three-piece suit" is first modified by "black" to form the nominal "black three-piece suit", and this in turn is modified by "immaculate" to give the interpretation "three-piece suit that is immaculate by the standards applicable to black ones".

By contrast, if a comma is inserted to give

an immaculate, black three-piece suit

then things are somewhat different. Here, "three-piece suit" is modified by a coordination of adjectives, giving the meaning "three-piece suit that is both immaculate and black".

Note: for clarity, I've ignored the compound adjective "three-piece", which is also a modifier.
