Above is 'transformational grammar'. Try a web search
for more details.
You also need to know that grammar is an overall term.
Actually, transformational grammar would be better called
transformational syntax (sentence structure).
But Noam Chomsky included both in the title of his book,
on the subject/s. Adding confusion to what was
supposed to clarify -:)

You can have a grammatical error in English with the sentence structure.
Try a web search for 'sentence faults'.
Or with misuse of words within the sentence.
that comes under the heading of 'usage.'
> 3) what is the semantic relationship between colors?
There are the primary colours but then shades of meaning.
Red is a primary colour but ruby, scarlet, pink indicate
deeper or lighter shades.
Check a dictionary or a thesaurus.
