Interesting. Is this some sort of of revelation about language. Seems plausible in some ways. My wife is a Speech and Language Pathologist and as an educator myself, we've had similar conversations about human perception and language. Not about colors exactly, but in language acquisition, some children with language delays have inexplicable difficulty with prepositional phrases and actually hearing language subtleties that so many of us take for granted. We joke about how a simple initial screening for students could consist of asking two questions. Question 1. Ask about the February holiday when people give gifts to loved ones. Children that reply ValenTIME's Day, even after being corrected, send up a red flag. Question 2. Ask a child to describe a time where they were playing a game against an opponent. Encourage the use of "versus". The use of versus as a verb is also a red flag. "I was VERSING my best friend in a game of checkers". Even when corrected, students with language difficulties will repeatedly make these same mistakes, as if they are interpreting the world differently than most of us.
