It’s not basic science. Leonard Sax’s ideas are outside of the mainstream in psychology and quite controversial, and as far as I know, even he didn’t get into color. Perhaps you can cite his writings on gender and color?
You‘re stating these things as facts, but they are not. I posted some actual historical facts earlier in the thread about a time in the early 20th century when boys were associated with pink and girls with blue. You seem to be ignoring that completely.
As a previous posted stated, most of the posted links are not scientific papers, so citing them as “basic science” betrays a lack of understanding of what basic science actually is.
