The usage of 是.......的.
Ok, so recently I've been wondering about sentences that end with the word '的'. I've looked at a few grammar books, and they basically say that this structure is used to focus on a detail of an event, with ‘的’ usually being used for past events and being omitted for events in the present.

An example of this sentence structure I have seen is:

- "你的车是什么颜色的？”
- ”是红色的“

So, I was wondering, why is do these sentences end with ’的‘?

Answer

Just because these words （such as 红色的，我的）are adjective. Lots of nouns can be turned into adjective if you attached a "的".

In fact, "我的车是红色的" is an abbreviation of "我的车是红色的(车)".

Answer

to make it a complete adjective

you can say 我的  车  红
or
我的  车  是  红色的

Answer

You can see a “是” before the “的”.
“是……的”is a fixed collocation,it's equal to be+adj. in English.

Answer

我的车是红色的=my car is red
的 expressing some relationships which include
 1. belonging = 's
 2. modified and decorated and trim(修饰，beautiful girl is decorated or trimed by beautiful )
我的车很红(✅，my car is very red but here isn't 是 in chinese. 是is approximately equal to be but completely equal )
我的车很红色(❌ 红色 = noun. You can say that the man is very America. But so weird )

Answer

Because you can just say
-你的什么颜色？
-红色
