Monosyllabic colors names (e.g. 红, 蓝) as predicates with and without 色 What are the different options for using colors predicatively? Particularly monosyllabic colors like 红, 蓝, 黃 that can appear with or without 色.

For context, here is a sentence using 红色 predicatively taken from a random Wikipedia article.
你   的    汽车     是不是         红色        的?
ni3  de0  qi4che1  shi4bu2shi4   hong2se4   de0
you  DE   car      COP-not-COP   red        DE
Is your car red?

The declarative form of this sentence is
你   的    汽车      是        红色        的.
ni3  de0  qi4che1   shi4     hong2se4    de0.

However, 红 is a verb by itself (unlike 咖啡色).
Is it possible to use 红 as the predicate of that sentence without the 是...的 construction? What are the different ways to use a short color as a predicate?
I can think of a few potential ways to do it, but none of them seem to work.
A) ?你    的   汽车     红
   ?ni3  de0  qi4che1  hong2 

(A) seems weird because the predicate is only one syllable. I think it breaks a Mandarin prosodic constraint.
B) ?你    的   汽车      很     红
   ?ni3   de0 qi4che1   hen3  hong2

(B) also seems odd, but I can't really say why.
C) ?你    的   汽车      红色
   ?ni3   de0 qi4che1  hong2se4.

(C) seems strange. I'm pretty sure 红色 is a noun and therefore cannot form a predicate by itself.
This question is similar to this one, but is not a duplicate of it because it's specifically about what things are allowed or disallowed in predicate position and why.
1， “Adj 不 Adj?” is just a short form for &quot;是不是 Adj 的?&quot;
For example, I drink a lot of wine and want to know if my face turns red, so I ask my friend.
Q: &quot;我的脸红不红？&quot;
A: &quot;你的脸很红。&quot;

2， &quot;adj 吗&quot; is an even shorter form.
Q: &quot;我的脸红吗？&quot; A：“你的脸很红。”

3， 红 can also be a verb but that means &quot;turns red&quot;, there must be a transition.
Q: &quot;我的脸红没红？&quot;
A: &quot;你的脸红了。&quot;
