Social cues primarily require prior knowledge of the person and the context to have meaning. Stating that something is a color with no additional context as to why that color has a meaning is confusing.

"Thst shirt is blue!"

Ok. I wonder if it is just a bold color, a team color, doesn't go with some other color they are wearing, or something else. A neurotypiczl person would probably just assume their first assumpton is correct but answer with a vague "It sure is!" they can both go on with their day whether they are on the same page or not.

The reason that this is my example is after having a lot of technical discussions that require shared understanding of details, it is apparent that the vast majority of people just assume they are on the same page when they are not. But they communicate in vsgue ways that don't cause issues as long as nobody checks to see if they really are on the same page.
